DOD 280 Compressor

Here we go with another classic optical compressor. Original unit uses VTL5C2, so could get away with using any LDR with 1M dark resistance. So the LDR resistor would be  resistor leads of VTL5C2 and that green LED acts as LED leads of the vactrol. Positive/anode to strip four and negative/cathode to strip one. Haven't built it myself yet..
