There are two versions of this amp; one auto-biasing and one manual. 1400.00 Sorry, this listing has ended. There are two versions of this amp; one auto-biasing and one manual. Mine is the manual bias version. I bought this amp on Audiogon in February 2012 and enjoyed its sweet and powerful sound for 6 months. I have to sell it now because I got a new SET amplifier. The amp is in full working conditions. Cosmetically it is also perfect, except for:This version, with its bigger transformers and better performance, is the SUCCESSOR of the highly acclaimed Cayin A88 (and it's definitely easier to bias). As far as I know, it is more similar to the Cayin a100 than to the A88. You'll find lots of good reviews online. Everything is included, even the white gloves and rubber dust jackets for the RCA jacks. It will be shipped in its bomb-proof original double boxing.Buyer pays Paypal fees.

Read 10023 times.I am wondering if anyone can give a step by step instruction on how to bias the powertubes in manual biased version.What would be the bias volatage for EL34 and KT88?Yes I have a DMM,no I never did this before. All you need to do is use the bias points on top pannel and adjust the pots. But unsure how to do it?It is very silly. I am wondering if anyone can give a step by step instruction on how to bias the powertubes in manual biased version.What would be the bias volatage for EL34 and KT88?Yes I have a DMM,no I never did this before. The bias should be set at 1.56mv for el34's, not sure if it different for kt88's. Jim If you meant.030 -.035VDC, then that is similar number value that EL34 prefers for bias current, 30-35mA. As for the bias procedure, it's usually something like this: Let the amp fully warm up, minimum 15 minutes or more. Everything, even iron core transformers should be fully hot.

Mute input signal. Connect your meter to the test points. Adjust the bias pots to the recommended setting. Check that all the pots are correct, as sometimes turning up one pot will rob from a previously adjusted pot. Once they are all stable and same value to spec, then you are done. Connect meter to test points and turn down the bias adjustment pot to minimum setting, using the meter to verify that you are at zero, and not full high. Some amps are fully clockwise, some are fully counterclockwise to achieve zero bias current. Never guess, never remember from last year, always check it. Tubes are expensive. Turning on the amp with full bias will fry the new tubes quickly. Once all bias pots are set to zero, then power off the amp, replace tubes, power on, warm up, slowly crank in 90% of the Cayin recommended bias setting. The meter reading will move up slower than the screw cranks, so you have to go slow, so you don't overshoot. Once you have all bias pots up to 90% and all measurements are stable, then bring them to 100%. With brand new unburned tubes leave meter connected for 30-60 minutes to make slight adjustments as they burn in. Then check it again after playing music for 1 day, 1 week, 1 month, then however often you prefer, probably 3-6 months. For JJ, or vintage 3 months, for New Sensor or high quality chinese 6 months. I checked the manual again,it also says bias voltage set at 0.30-0.35 volts.Steve from VAS mailed me few hours ago to set KT88 bias voltage as 0.4V at A70T.So not sure why you said 0.030? So places where EL34 is used one can not use KT88 due to higher bias current needed.What about using EL34 where KT88 has been used ?I am asking because A70T manual biased version comes with KT88 ? The yellow light on startup is the triode mode and red light indicate ultra linear mode. Thank you for all your helping hands. By using our site, you consent to the use of cookies by us.

I realize that with full manual that you cannot push a button and have the needle move over and down automatically, then return home when the record is over. I don't mind lifting the needle onto the record manually, but what happens when the record is over. Does the needle just lift up or something?Youse got a problem wit dat? Otherwise the 'table will continue to turn and the stylus will continue playing that inner groove until the cows come home.So - why does anyone buy a fully manual table??? Well - here's the thing. They're usually better tables for a couple of reasons: 1) Automatic tables are usually going to cause more record damage than manual tables will, especially on the inner grooves as the tonearm reaches the end of the record. Most automatic tables use a mechanical device (spring loaded switch, etc.) on the arm to trigger the arm removal at the end of the record. These devices typically add additionl resistance to the travel of the arm and stylus as it reaches the end of the record and can therefore cause those areas to wear faster than the outer grooves - hope that makes sense! 2) The motors on manual tables run at a constant speed and are therefore typically more accurate. 3) Your tonearm upgrade path is usually very limited on non-existent on automatic tables. This isn't to say that the Thorens TD170 may not be your best bet given your needs - I'm not at all familiar with it since I've only always owned manual tables. Just some things to consider though.I'm usually in another room or asleep by the time the record ends, and leave it up to me to forget to go lift it up. It would just stay turning until I went to play another record so that would probably be more damaging than an automatic tonearm. As far as upgrades, I won't be upgrading. I just need something basic to play the few records I have. The only upgrade I would probably ever do would be a new cartridge, although the Thorens comes with an Orotofon 10 which might be fine.

I did buy a new Grado Black cart for it (seemed like the best el cheapo one out there) and I'm very happy with it actually. It sounds great and outperforms CD by a long shot. The only real reasons I want to get a new one is because I WANT a new one. All the tables I've ever had have been used. Plus I want belt drive, and I want it black (this one is silver.sticks out like sore thumb!).

It uses four KT88s or EL34s for Class A2 P.P amplification. The toroid power transformer and EI audio transformer are specially manufactured with low magnetic leakage, wide frequency response and low impedance. Two 12AX7EHs and two 12AU7EHs are used in the preamplifier.

Works with KT-88, 6550, EL34, 6CA7, 6L6 or KT66 tubes. There are output taps for 4, 8 or 16 ohms. One very cool feature is the ability to switch between Ultralinear and Triode by remote control. This amp is hand built with point to point wiring; the best method available. Components are high quality audio rated and solder is silver bearing. I contacted Cayin sales before purchase and they clarified the differences between this and the US (VAS Industries) version. This amp was designed powered and tuned to produce the best sound quality from the tubes used. The US version was altered to produce more power for most likely marketing reasons (bigger is better right?). This version uses true tube rectification where the US version uses the less expensive and less desirable solid state rectifier. Note the tube remained in place on the US version so no cabinet modifications would need to be done, hence the complaints online about bogus tube rectification. This version uses a two stage adaptive auto bias. The power output drove, Gallo Reference 3.1, Monitor Audio Studio 20se, and Dynaudio Contour 1.6se to levels way beyond comfortable with nary a hint of distortion, rock solid bass (in ultra linear) and sweet extended highs. A note of interest is that UL is roughly twice the power of TR yet flicking back and forth on the fly the difference is subtle both in volume and tone. Don't let the numbers dissuade you. This amp has plenty of power and control. There is a snap on tube cage to protect the lovelies which I left off because I love the warm glow of the tubes at night. The tubes are matched quad of Electroharmonix with Electroharmonix 12AX7EH and 12UX7EH and a JJ rectifier. This is a beautiful looking and sounding integrated that can be used as a power amp. It has exceptional build quality and a very versatile feature set. It's easily one of the best I've owned.

Ultra-linear is not as open and three dimensional as Pentode mode, but Ultralinear is what most tube audio manufacturers use to keep costs down, operating in Class AB1, not Pure Class A. This piece is hand built, including point-to-point wiring. Point-to-point was the way that amps used to be wired back in the 1950s and ’60s when high quality circuit boards were not available. Today, point to point is an attribute of electronics built in low wage countries, such as Asia, this process cost less. Point to point is old school. The cage simply snaps into place, so that you can take it on and off with no problem. Keep it on if you’re worried about protecting your tubes, or take it off to show what real, heavy-duty, classic tube gear looks like.

If you've ever gone to a manufacturer for recommendations on what else to use in your system, you probably found out that a lot of them are reluctant on the subject. Recommending some brands at the expense of others is not always politically advisable. As it happens, a Cayin rep tells me that the reason he investigated the line in the first place is because as a representative of the US manufacturer, he was approached by the latter about the amp. One need not be a savvy industry insider to take one look at the Cayin and observe its market-friendly aesthetics. It's one great looking piece of amp.

I suppose one thing that sets it apart from the influx of born-and-bred-in-China components is that it's actually bred in Germany. It's only manufactured in China. I'll leave it to the reader to decide if that's a notable distinction. I only mention it because one slam I'm hearing on Chinese products is that thus far, the Chinese have succeeded only in cloning equipment but have yet to begin to design their own good stuff. I have no idea how true that is but it would seem that Cayin would want you to know of its Germanic roots. While on the subject of cloning, there's something else that I find interesting about Cayin. They claim that they design certain pieces to sound like other classic components. In the case of the A-88T, they claim it to deliver the sound of the classic McIntosh MC-275, which I've never had the pleasure of hearing and upon which I'll thus not be able to comment. Hand-built and point-to-point wired, the Cayin is said to be built the way components were back in the 1950s and '60s when cost was not the primary objective. I guess there's a certain amount of truth to that. But once you see, as I have, how a manufacturer sweats the details as he tries to move a point-to-point wired prototype to production featuring well-designed circuit boards, point-to-point wiring looses some of its distinction. You see, most prototypes are indeed hand-wired. And that's fine unless you manufacture where labor rates are high. In which case the next step is to design a circuit board that sounds the same as the hard-wired prototype. That's not always easy. I've seen projects delayed or cancelled when a no-compromise designer couldn't make that transition and maintain the integrity of his original design. Of course, the reason for going circuit board is to reduce assembly cost and thereby final pricing to reach a wider audience while maintaining consistency of manufacture.

True talent and true care for the customer would force this designer to take his product to the next step, to not only make a product more affordable but more reliable. I do digress, though, don't I? That's because little of the above pertains to the Cayin A-88T. It's built better than hand-built products from other areas of the world selling for multiples of its price and then it sells for a fraction thereof. I just burn a little about the disingenuous marketing hype propagated by some who would make excuses for extremely poorly built products based on the fact that it sounds good and how their designer is supposedly a genius. Give me a break. End of rant. It is true, though, that point-to-point can sound better than a poorly executed circuit board. If Cayin can pull it off with a solidly built and affordable product, good for them. And you. I had none of those in house. It's also switchable from the remote control to produce 22 watts in triode, a neat touch. The rest of the tube compliment includes a pair each of 6SL7 and 6SN7 tubes. Frequency response is stated as 18Hz to 35kHz, no tolerance given. THD is listed as 1% and the signal to noise ratio is said to be 90dB. Input sensitivity is 260mV (integrated) and 600mV (pre-in). The Cayin A-88T weighs a solid 55 pounds and consumes 280 watts at the wall socket. Premium parts are said to include chassis-mounted ceramic tube sockets, an ALS volume control, Nichicon and Realcap capacitors, WBT style speaker terminals and gold-plated input jacks. Warranty is three years parts and labor, 90 days on tubes. Around back of the A-88T the user will find the aforementioned WBT style shrouded binding posts, four of them per channel. Unlike some amplifiers that tap the output transformer at one fixed impedance, the Cayin allows you to connect for a 4, 8 or 16-ohm load. No more guessing if your amplifier is optimized for your speaker load.

The A-88T allows for three different line level component connections and also features a pair of preamp inputs that bypass the A-88T's passive linestage, transforming this integrated into a basic power amplifier in the process. Inputs are labeled CD, Aux and Tape. Does anybody listen to tape these days. Of course the A-88T also features a fuse-protected IEC power inlet. It's a solid if little remote, milled of one piece of aluminum. The only thing strange is the fact that there is neither a little door providing access to the batteries nor any visible screws with which to remove the remote's rear panel. I suspect that removing the 4 rubber pads on the remote's bottom panel will provide access to said screws. Utilizing only 8 buttons, the SP05B remote allows selection of the source as well as control over volume, including a full mute. As I indicated before, it also allows on-the-fly switching between ultralinear and triode modes, each indicated via a differently colored LED on the amp's face (upon power-up, the amp always defaults to triode). Should the remote control ever be misplaced, little is lost. All of the remote's functions are duplicated on the face of the A-88T - with the exception of mute, which would be silly as the volume control is right there. The pictures tell just about everything else there is to say about the front of the A-88T proper. It's highly finished with many touches that indicate attention to detail. The A-88T features a 30-second soft-start circuit that gently eases into powered status. Given that, I was a little surprised that power down as well as source selection caused an ever-so-gentle transient. Not so much that you'd ever worry about the amp or your speakers but it just came as a little out of character. That was the single rough edge on a very smooth design. Or perhaps striking is a more appropriate description. Ah, I've got it. Call it strikingly glorious. Yeah, that's it. Nope, that's not quite right either.

The 88T sounds impressive and the characterization is certainly accurate. But it doesn't hint at the amazing sense of transparency that projects forth from the 88T. Of course that big and open sound is largely due to that marvelous degree of transparency. So maybe I've made that point already. The Cayin 88T is as transparent and strikingly glorious an amplifier as one is likely to find at its relatively meager asking price. Or well beyond. Okay, I can live with that characterization now. Why so much to-do trying to sum up the Cayin 88T in one line so early on in the review. Well, truly, upon firing up the Cayin, you immediately notice that there's something different about it. It doesn't require extended listening or acclimation in order to unearth the magical qualities of this amplifier. It's immediately obvious. It's different, it's musical as hell and it's flat-out enjoyable. Within minutes of hearing it, most listeners will likely have already come to the same summation. You won't have to think about it. You don't have to analyze it. It'll just hit you. You can't miss the added sense of life that the Cayin brings to the music. (As you can tell from the next picture, this little amp quite inspired me to have fun in Photoshop.). We've just launched a dedicated AudioMart in Russia, UK Audio Mart.

Point-to-point was the way that amps used to be wired back in the 1950s and '60s when cost was not the primary objective.

Nowadays, most everything contains circuit boards instead of this point-to-point wiring, which is much more dependable and better performing. It's one of the main reasons why these Cayin pieces sound like the classic tube gear from Marantz and McIntosh. There are output taps for 4, 8 or 16 ohms. This allows you to fine-tune the sound that you desire. Switching is simple, and listening to the differences is a lot of fun. This amp is manual biased. There is a snap-on removable cage, so that you can take it on and off with no problem. Keep it on if you're worried about protecting your tubes, or take it off to show what real, heavy-duty, classic tube gear looks like. Turn off the lights and watch 'em glow.

If you're after tubes, post over here.In an attempt to get right to it, I was wondering if there's anyone out there who might have some knowledge of this amp happens to know the plate voltage. The manual is relatively useless, even though it gives a recommended mA biasing of 35 - 40mA for the factory KT-88s, which seem to me a bit too low (however, if it is indeed correct, that would mean the amp's plate voltage would be at or around the 550V range for that kind of recommendation, right?).

I have tried measuring the voltage with a Radio Shack 29-range multimeter, but with no luck, as the reading remains at 000V when trying to measure up to 600V. It could be I'm simply not using this particular model correctly. At any rate, any information out there would be greatly appreciated.
