This is unusual. Do you have access to a signal generator and or an oscilloscope?
Bill,
I thought that too, which is why we wired up the second one to test. We are getting same results on both of them. Another club member has a V3 board, and his has plenty of audio. This made me suspect that the V4 board might have a problem in the audio chain, I understand that the V3 had an IC amp, and the V4 has a discrete amp. I haven't looked closely enough at the board to determine if that is the case, thought I'd see if others had seen the problem first.
