I just finished this build, and everything looks good, but on channel 4 the left audio is lower volume. The left and right channels are equal volume when the knob is at 10 o'clock. Where should start troubleshooting this? I've tried reflowing the main and VCA boards, but I may have missed something. I plan to go back under the scope and take another look tomorrow. Sending an envelope to the volume input works on all channels. So does the pan CV, scan, and span. Because the left channel is of lower volume, the audio isn't equal until the pan knob is at 10 o'clock. Thank you!

I'm putting together an order for a Stereo Sum (Main), 3x Stereo Sum (Channel), 3x Stereo Sum (Mono Channel), with a Stereo EQ. I'm starting a parts order and I noticed that on the BOM for the Stereo Sum (Main), under value, it says 1x A100k for volume, and 2x A100k (T18) for HP_VOLUME, MIX_HP_LVL. Under Package it says 1x B100k Dual Gang Stereo for Volume and 2x B100k Dual Gang Stereo for HP_VOLUME, MIX_HP_LVL. I'm guessing that I need 1x A100k Dual Gang for the volume and 2x B100k Dual Gang for HP_VOLUME, MIX_HP_LVL. Is that correct?
