Please help! I goofed up big time hooking up my gssl turbo mod and accidentally flip flopped the connections to the control board and swapped most importantly the 12v and C solderpoints and fed my turbo board +12v to the output and vice versa. I also swapped the -12v and 0v with the G and D points. I didn't test the voltage before I started and when I turned it on it somewhat worked but was outputting extremely hot signal. after I figured out the mistake and rewired it I plugged it back in and was not passing audio on the left channel. When I powered it up and down there was a slow peak in signal on the left side but no audio passing. I tried swapping the vcas in the L and R audio path and it worked in standard mode again, but now it appears the turbo mode(which is switchable) does not appear to compress much/at all compared to the standard setting. My suspicion is it's only getting half the signal when in turbo mode).
So I guess my question is where should I start looking to fix it? Did I burn up my turbo sidechain vca and/or tl074? Did I burn up anything in the left channel audio path? Should I replace all the vca's and/or opamps for good measure? How does one test a vca to see if it's working short of plugging it into the working part of the circuit for comparisson?
