Hello everyone,
the last days, I've builded my first Hairball 1176 rev D and now I have a little problem.
The input XLR is fed with a 1kHz Sinus tone from the daw with 0,775VAC (meassured), but trimming the Input pot on the front up from lowest to 40 lets the VU Meter (+4 mode) goes to Maximum and the Output transformer buzzes extremly. It doesn't matter where the Output pot stands, the Output XLR has about 26VAC in this case. Also, the Output pot doesn't work correctly because it can only trims 4dB up or down.
I've checked twice everything but can't find any problems :-( Does anyone has an idea?
