    Just made a crude frequency response measurement of the right channel on my oscilloscope. C1 is OUT+ and C2 is OUT-. At about 1k Hz the amplitude of OUT+ drops by about 1 dB. Anybody know what might cause this? Maybe its because of ZF?

    Just got the first channel of my CFA3 build up and running. Got the bias dialed in at 150mA. Everything seems to be fine, though the Pk-to-Pk voltage of the positive output is about 1V lower then the Pk-to-Pk voltage of the negative output. Is that something to be concerned about? Seems to be slightly frequency dependent.

    Can anyone tell me what the single 10k trim pot is for on the CFA3 board?
