Hi,
I've been working on the g1176 as my first project, and have run into a problem I can't seem to sort out. My unit is working as a gain amp, as in signals go from the input to the output, and I can adjust the levels with the pots. However, I cannot get it to compress. The VU works great in monitoring the output, but when I try to zero the meter in GR mode, the needle will not go past -10, nowhere near 0.
My DC voltages all look fine, I had no problem with the Q-bias adjustment, and I have replaced the TL071 and Q10, thinking there was something wrong with the GR driver circuit.
I'm using OEP transformers in and out, and mnats board.
I've been working on this problem a good week now with no progress, so I'd really appreciate some assistance.
Thanks alot.
Warren
