I'm trying to troubleshoot my G1176s, they are working, but have a few issues:

1. Input gain - I have a 10k log pot there and I have some heavy limiting occuring starting at around 1-2 on the dial. This is with signal from a CD player's unbalanced line level output. Could this be Q bias related?

2. Because I can't turn up the input gain with limiting occuring so early, output gain is fairly low. In bypass, I am able to get the 1.23 Vrms which is +4db level, or 0db on the meter.

3. The ratios seem to be backwards. I checked the wiring, but both channels I built react the same way. I'm going by the GR readings while changing the ratio - the 1:4 setting has way more reduction than 1:20. What could cause this? My markings are fully CCW to CW: 1:4, 1:8, 1:12, 1:16.

It still seems there is no 100% clear calibration for the G1176, I've had to piece together between the original manual and the newer method. I wouldn't mind putting one together, but I don't know if I am right!

Thanks...
