So I'm having some crazy issues with a turbo board I'm trying to install into an already working GSSL build. I tried reviving an old thread with similar issues but didn't get any response. Please help! :'(
So the problem: When the turbo board is connected, and ICs socketed, the meter pegs when taken out of bypass. If I set the ratio @ 2:1, attack @ 30ms, and release @ .1s I can get the meter to show somewhere around 12db of reduction. A little more "gain reduction" as I slow the release, but any other attack or ratio setting maxes out the meter. Threshold and output pots don't affect the meter.
I've taken voltage readings on the TL074 socket and they don't seem normal:
1: 3.18
2: 3.41
3: 0
4: ~12
5: 0
6: 0
7: 2.8x (drops slowly in .01 increments when taking reading)
8: -.04
9: -.04
10: -.01
11: ~-12
12: 0
13: 3.41
14: 3.71
Also, my point "C" reads 0vdc when engaged, .05 when in bypass. And I've measured that resistance is switching across R6, but values seem a bit low.
Sorry for the info dump, but I tried this thing connected every appropriate way I could imagine. Switched turbo and hardwired turbo, I've lifted and tested all the resistors and diodes, and still it persists. Without the turbo connected the GSSL works as normal.
Any thoughts? ???
