Hey
I've been working on a Tube Screamer circuit with all of the mods. I posted about it on this thread but I have clearly bitten off more than I can chew.
I have put it together and it passes signal so that's a win, however there is no gain. With an audio probe I have tracked the problem to IC1.1. The signal enters strong on pin 3 but comes out extremely weak from pin 1 and therafter.
I measured the voltages and they are as follows:
I put a bias trimmer going intyo pin 3 of IC1. The scematic says 1m but I only had a 470k trimmer. The trimmer celarly affects the circuit and I can get some cool tremolo sounds at some settings or splatty fuzz. But still it's too quiet and not clipping.
Does anyone have an idea what I have done wrong here? Any help is appreciated.
