    The Headcase Stax thread

    Were there measurements of width and length, more pairs available? Could maybe fit U70.

    Thanks all. Gonna be fun finding one of n:th solutions.

    Any suggestions on how to best place the power supply and amp boards before I start drilling? Transformer's place is given, and maybe the power supply should be placed at the back too with the amp boards facing the front (right). Thinking of hum and heat issues. Tubes will fit inside the box but I suspect holes on top lid above the tubes would be beneficial - top lid only has those small ventilations on the sides. Depends how hot the KGDT runs.

    Thanks. Let's see if I get them running with an adapter.

    The Headcase Stax thread

    Amphenol plugs above. Would it work having a common bias for L/R connecting Beyer ET1000 to a Stax amp? And does anyone know the pinout for the Beyer?

    Goodbye Tyll. Happy Travels

    A loss that Tyll retired. Wonder when that site closes down, haven’t read anything worthwile since his departure. Any news from his roadtrip?

    Anyone got a surplus 6-pin Amphenol plug or similar?

    What's the output impedance of the cfa?

    I got the NAD20, are those the same drivers? Doesn't sound too bad but not good enough to spend too much time on. Not Stax pinout. What about the diaphragm specs?

    Pinned thread has dissappeared

    Nothing stopping starting a new, often helpful in builds.

    goldenreference low voltage power supply

    Thanks for info - seems the voltage was just at the limit of the regulator's range. Changed back to original 1,5K resistors (from 1,8K) so now DC out is 19,5V (before 21,5V) from a AC18V transformer. All leds are on. Problem here is the mains moving from 210 to 230V and those swings seem to affect the whole GRLV system.

    goldenreference low voltage power supply

    Leds close to big caps light up, then dies. Same thing when powering up once again. Other leds unaffected. Amp boards OK (Dynalo). Any ideas what it could be?

    transconductance amp

    Is the amp sensitive to pulling the headphone plug while playing?
