    I like how its all exposed--might as well be able to view the good stuff right? Although I think I'd probably at least put some plexi over it or something. Probably does have a cover that's just not on right now though.

    Agreed! There is a cool factor involved plus it's on the outside of the cabinet away from any internal vibration or resonance.

    Absolute BEST Analog Volume Attenuator Ever Created By Humans Thus Far!

    It's ultimate construction make this Attenuator sounds even superior to the $1200 Alps Attenuator.

    Is that supposed to be the ALPS pot? Looks like it says Matsu****a to me. Or are they one and the same anymore?

    Yep. It's made by Alps and same POT with Alps name is sold to the select few audio nuts for $1200 a pop.

    I think Alps is OEM for Matsu****a or Matsu****a makes Alps.

    AFAIK, these pots are made only for a short period and supply is very limited. And all known supplies are secured by Accuphase for service and support.

    Of coz, Accuphase charges not less than twice of what Alps sold to them. The name says it all.

    WOW,thats cool James.Accuphase have always made top quality products and that pot explains in part why they their units cost a small fortune.

    Sorry, but the best sound will always come from a stepped attenuator using high quality precision resistors. That may be the best sounding potentiometer, but not the best attenuator. Don't believe everything you read on Axel's site.

    EDIT: OK, I read those are actually motorized stepped attenuators. I can tell by the construction they are by no means the best in the world. Sorry, that would be something like a Goldpoint or Elma with Holco resistors. There is probably something better than that also, but those are the more mainstream available ones.

    Ok! I love to see the best Analog Attenuator design by date. Yeah, I've seen most of it.


    Don't believe everything you read on Axel's site.
    Nope! Pure Experimental and having heard over a dozen of High End Preamps side by side and learn the differences, I came to the conclusion. I don't talk with other's mouth. I read, I study, I experiment, and I talk.

    EDIT: OK, I read those are actually motorized stepped attenuators. I can tell by the construction they are by no means the best in the world. Sorry, that would be something like a Goldpoint or Elma with Holco resistors. There is probably something better than that also, but those are the more mainstream available ones.
    What did you learn from the construction. Do you know what the circuit board in the background means? It makes the whole concept so special to track and correct the resistive arrays elements on both L & R to 0.5dB (more like 0dB) at any volume. The front step attenuator should have been enough but they included the motorized resistive array and error control mechanism for resistance compensation.

    As usual, the Japanese companies don't provide any information on the Technology. Even TVB don't have the complete info on these. Coz these are Pioneer Highest Line Exclusive and not to be seen in the U.S. I have seen Accuphase, Luxman, Boulder and FM Acoustics designs. Everyone does things differently but yeah, I will repeat this is the highest order of the design and implementation of (Full) Analog Attenuator.

    Sorry Mike! As the resistors, yeah! But for use as Volume Attenuator. Nope. No error correction method but again Z-foils are very high precision grade, so error correction may not be necessary. But even small errors adds up when added.

    Thanks Fred! As I learnt it; C-290V is the last Accuphase Flagship preamp with real Analog Volume Pot. They have switched to AAVA after the C-290V. I've heard that makes the previous AAVA preamps sound a little thin but now they have further refined the AAVA technology and their newer ones are hardcore.

    Basket case (scrap metal pile find) Marantz 2220 (predecessor to the "B" version). Hefty durn piece of soiled state equipment. Probably can't tell from the crummy available incandescent light shot, but the front panel markings are all engraved.

    An afterthought,, the three film caps at the top of the picture (.22uf/480volt) are apparently bypass caps,as each one is on a big blue electrolytic,,would I hear any difference or increase performance by upgrading them? Also,, there are two smaller caps(.056uf) caps between the 12FQ7 and 12BH7 tube.I'm probabally gonna replace the bias resistors cause' the amps are about 16 years of age now.BTw--I was really knocked over by the way all of the components had "precise" bends in the leads,looks like alot of forethought and planning went into the production.I also should say that I've seen the work of Jesse,Rich,Jerry, and Ben,,, impressive to say the least,as when I looked inside the amp last night,I was reminded of you guys.

    Here's one of the Quicksilver GLA 40 watt tuber,,can you tell that I'm kinda bored? Pulling the bottom covers off my amps,,man this economy is killing me,,throw in the Georgia weather doldrums,,and you have a recipe for funk.Or maybe just blue.

    Seems like many of you are not getting the point of showing the "ass(embly)" first.

    Two weeks ago from my favorite vintage audio emporium; Kenwood TK-88. Finally got around to testing (and cleaning the controls); works well (and, yeah, those 40-plus year old electrolytics should all be changed...). Good tuner performance, as one would expect from the Kenwood folks; Kenwood/Trio was and (AFAIK) is first and foremost a radio company.
