Re: LA500A opto comp leveling amp BUILD THREAD 500/51X

Hi Joe! Just finished building my LA500A, I have a question about the small LA500SCv2 PCB, there is a procedure to adjust the 4 trim pots for the VU meter but on the procedure there is one trim that you don't talk about that is R18 ST Match Up trim, is there any setup procedure to do with that trim?...
