made this little helper for the multi simple hpf in the sidechain if anyone needs heres the info. board will fit the 1HE front panel and the footprint fits the standard Lorlin 6x2 Rotary SW and wima caps (5mm).
I have a few boards if you need get in touch. if you want to get your hands dirty etch your own - file attached.

The difference between THAT2180 Type B and C is max.THD 0.02% vs. 0.05%. I wouldn't care for these worst case -66dB vs. -74dB control voltage (not audio) differences when parts tolerances between resistors and capacitors are much higher. As always YMMV.Is it important or not, for them to match? (Side chain VCA & Turbo VCA)
Do you mean disconnect the L, R and return wires to the SSC and put a couple of 47k's back into the main board?+1
Disconnect (or cut in middle) the three blue wires connecting to the 47K pads.
Put the two 47Ks onto the wires.
(Can easily reconnect wires later)
All voltages were correct on the main board, I didn't check the voltages on the SSC board.Did you check voltages on the boards (IC pins) before powering up with any IC inserted anywhere?
I've just swapped out the L, R and return for 47k's and still the same issue.Yes. The ones that you labelled L, R, Ret. Or reinsert 47K's on PCB to test.
Either way, need to confirm the comp without SC board functions correctly and that all voltages are OK also on the SC board.
Another source of dysfunction you need to consider next is the bypass switch wiring (black wires) and/or the hookup of the switch you used. Other users reported problems with their switch wiring.
