  1. Either that or just DL the rips off the web.
  2. We could do one amp to rule them all but what would be the fun in that...
  3. The lack of a proper dust cover on the back of the Lambda Signature is the culprit. It uses the woven mesh but no thick layer of mineral wool to keep everything out of the driver.
  4. Compressed air and Stax drivers do not mix!!! The film Stax use for dust covers is very fragile so holes in them after some use are not uncommon.
  5. A 3U unit has a lot of air in it so you should be fine without a fully vented bottom. I hate those inner bases and my bottom panels always look perfect. :ยด)
  6. The squeal? Dust or some debris inside the driver making a partial short between the diaphragm and stator causing the diaphragm to oscillate.
  7. 007Mk1 or the SR-Omega do make the difference more apparent. Also choice of music is a factor but at the end of the day the KGSSHV is pretty fucking awesome.
  8. It could be a noisy pot in one channel but this sounds a lot like driver squeal.
  9. I've used 1.37K in my amps and it works well with the 1K pot. 30VAC to 36VAC works fine for the LV supply. You burn off more headroom with 36VCT in the regulators but the front end uses so little power that it doesn't matter.
  10. Congratulations indeed as it takes skill to pick two lackluster amps in this day and age.
  11. Increase the resistance of the 300R resistor in the CCS. Going to 402R would be a good first step,
  12. Mine have a lot of holes underneath the boards so that's a good way to go. Still the KGST runs very hot but if heat ever becomes a real problem you can cut the current to through the tubes a bit.
  13. No problem testing just the LV side of the amp alone but it won't tell you much aside from "didn't blow up". I would recommend holes for that chassis... a lot of holes. Either that or dial down the current for the CCS as it should get very toasty.
  14. No problem using the RN60D, I've used them in all my amps. The diodes need to be isolated and the right voltage but other than that just use what ever you can find.
  15. When dealing with stuff 91V zeners are good to have around.
  16. I don't see any reason to do that.
  17. Yup check the zener string. I just looked over the layout file for the PCB and didn't see anything wrong.
  18. Mikhail was entertaining. Woo has some of that same epic fail but from them we get zero creativity, just crap engineering.
  19. Some PCB's arrived today which prompted me to take this photo, how far we have come in 4 years: On the left the brand new mini KGSSHVk stereo board and on the right the first version KGSSHV mono board. Naturally to make the stereo board we had to make compromises so only the output stage is on full size sinks while the gain stage active devices and the CCS sand share two sinks for both phases. That means I had to pick a CCS type and IXYS it was just to make it easier to build. Only K170 input fets are supported but this one does have servo which the old design didn't have.
  20. Moar holes is better... Not sure what I'm going to do with the ES-2 PSU box. I'll find some use for it befitting the name on the front...
  21. Nope, he used the Plitrons but they are just stupid. Heavy metal casing and who needs two 285VA transformers for that amp? Makes no sense when one 300VA unit is utter overkill. It will get custom made PSU too with the C- built in and everything crammed into one box...because fuck you Mikhail. I don't need an amp that is that heavy and almost a meter tall.
  22. Not sleeping is what I do....
  23. Sounds plausible... In Stax news Kevin felt I didn't have enough stuff to work on so he's sending me his Single Power ES-2 to rebuild. I said hell no to those crazy transformers Mikhail used so I can come up with a whole new PSU design. Should be fun and a whole crapload of work. Also the Chinese KGSS clone came in from a loan with the volume control busted. Had to spend some two hours yesterday rewiring it completely but now it works perfectly and some people will not get it back on loan...
  24. Ditto on Zonealarm. Been using it for years just for this purpose.
  25. Good for the mono crowd...
