I recently bought a balanced amb ß22 - just to obtain some populated boards for a two channel build for myself.   Since I already got a power supply and torriod, I now have a complete kit to sell.   You get: 2 populated Beta 22 boards, built from glassjaraudio kits (muse caps, dale resistors...), gain is set to 5 1 populated Sigma 22 board, built from glassjaraudio kit, Voltage 30V 100VA torroid (sufficient to power a balanced build)   Trying to sell this stuff...
Is there another PH for sale now?
Hi there, I'd like to create my own cups for the Th X00 and so I am looking for some help. Of course I could simply measure everything, but I think there are people here that have done that before and eventually with better tools and techniques. I have access to a fearly good lathe and (through a friend) a CNC machine is also at hand. So if you got any data, drawings or whatever let me know. Greetings from Germany Sathimas
Hi there,   I'm looking for construction data to make my own custom wood cups for the Fostex TH X00.   Just pm me if you got something.
Adding my newest observation:   Had the phones connected directly at turning on the amp, had no hum when the e12 let the signal pass.   Got hum, starting quiet and becoming louder after a few seconds, the hum started to "oscillate" getting loud and quiet at maybe 1  volumen-change per second - then the e12 started to switch on and off.     Any idea where the problem might be?
Well, this amp is driving me absolutely mad.   I changed the resistor-values according to ambs website to decrease the sensivity of the e12.   While doing that, I changed nothing about the internal wiring of the amp. (It was hum-free before)   Now after getting the e12 (half) to work (still a bit jumpy) the hum is back.   Changed the ground wiring to cavallis alternative wiring then with no effect - changed to normal ground scheme and the hum was gone.   For...
no offense taken.   Ground wiring on the EHHA is really confusing ...
