  1. Is that the Accuphase fanclub?
  2. GBU810 is fine for this and no need to match anything except the input fets if you are using single units.
  3. The 1uf cap has to be 25V+ so anything with 15mm lead spacing will work. I use 250V Panasonic caps which fit perfectly into the footprint. Kevin posted the part number either here or in the KGSSHV thread. The 100nf caps should be rated to handle the B+/B- plus a bit of headroom. We've normally used 1000V caps here but 630V also works. The rating of the input fets doesn't matter, just as long as they are the same grade on both channels. I normally use LSK389 B series and BL grade 2SK170's. Now that the BL units are almost finished I'm moving to my GR stock. Here are the heatsinks, big one for the CCS and pass transistors: 532-530002B02500G and the small one for the 10m90 CCS in the PSU: 532-581002B02500G Remember to order the proper insulation pads, shoulder washers and you also need 6/32" screws (either nylon or peek) for the small sinks.
  4. Forgot about that particular bit of madness.
  5. The balance pot should always be 2K but the offset needs to change with the voltage. Last one I built used 1K pot and 1.37K resistors at 400V but 1.5K should be fine at 350V. This resistor has to be 1/2W and higher wattage doesn't hurt as it gets hot. 24V is better so use that. Those are the correct LED's. Yup, we forgot to change the zener string values.
  6. All amps sound the same -Peter J. Walker
  7. Parts on backwards, pads screwed in place, pads backward and the spring missing.
  8. Yup, that would be the fart. Could be worse that usual on that set. I've seen some massive stupidity recently with the 007's and replacement parts.
  9. Alcohol works unless the diaphragms have suffered some sun damage so they are too fragile. Also look for oxidation on the bias contacts. That was 4+ years ago but I probably just copied what ever Stax did on the + input.
  10. I didn't do the final layout of the that board...
  11. Yup, those are fake as with most of these things from Dalbani.
  12. Around 1300Vppss and the gain is 500/1000 Edit: An updated on the KGDT is in order. First run of PCB's is here and I'm assembling them when I find time from the other 12 amps I'm working on...
  13. Lack of anything relevant for a long time now means nobody cares about EC. A bit like Ray in that regard. Pfft who needs fets when we have bipolars...
  14. It's hard to fix something like that. It's simply Stax caught up in the "OMG this new film is awesome" BS so hopefully they will make something less glaring next time around.
  15. I think nobody cares about EC anymore so Cavalli has to be their new champion. I mean the Lau is a piece of shit which will proven soon enough when I buy one for Kevin to rip apart. To people who know fuck all about circuits or amplifiers in general it must be a godsend though as it hides how crappy the rest of the system is and it costs a lot. The latter is especially important to further back up the illusion that it isn't actually terrible.
  16. The 207 is even brighter but for the price they are hard to beat. The brightness is nowhere near as bad as the 507 otherwise they would get to know a hammer up close...
  17. Looks real to me.
  18. I don't think there is a terminal block out that that can take 600VAC. Nice work John.
  19. So a notoriously bright-ish headphone sounds bright off a highly transparent amplifier? What an utter shocker we have there... I do like the comment that the amp somehow makes the source sound non-analog. How the fuck is that possible? I guess these fucktards are confusing analog and lush as no MSB source I've ever heard sounds lush. A bit on the dry and sterile side would be closer to the mark but that's what one expects from something as ruthlessly revealing.
  20. My first all black KGSSHV: Soft white power light...
  21. This would be a good example of not real... http://item.taobao.com/item.htm?spm=a230r.1.14.274.VYCKXq&id=35575378373&ns=1#detail I might have cleared out that place in Japan as I just bought a lot of 1968's. 1967's also work but then you have to insulate them. See here: http://www.diyaudio.com/forums/swap-meet/34929-fs-sanyo-2sc3675-2sa1967-hi-voltage-transistors.html
  22. The depreciation of the LLmk2 I was just offered is in excess of 60% is less than a year so people have to be bonkers to buy this crap. I truly love the use of the 6S4A as a gain device and not the output tube. Let's not use the component that is perfect for that role, nope let's use some high capacitance mosfets instead. The LDR is also too stupid to fathom and that on top of the drv134 distortion means pure win.
  23. The SR-3N was always one of my least favorite ones. I do own mint sets of all of them though.
  24. If you are a sponsor over there anything negative about you will be removed but if you won't pay, nobody gives a fuck.
  25. That's good to hear. :´)
