no shorts to the front. it was working for the past couple of years, then one side stopped passing audio. turned out to be a bad solder joint, and since fixing that I noticed this issue. i built it with turbo + 2 supersc pcbs. When I set the sidechain to EXT the meter drops back down to 0 after 3 short full scale pulses. When I set the sidechain to OFF the meter maxes. At 60Hz and 90Hz it pulses 3 times and drops down to 0. I also removed the extra mods and put the 47k resistors back in for the sidechain input, and am not using the turbo board either, and the issue is still thereshorts in the cable/connection/soldering to the frontpanel pcb?
