There are 7 trimmers that can be adjusted when the main board is accessable
1: near "S/SENCE" pot: Bottom freq F2 pin 10 LTC1060 to around 1000 Hz
this means Freq 2 on minimum and all modulations neutral/off and no MIDI connected
2: near "DEPTH" pot left small : Nulling LFO depth F1 set to hi reso and listen for maximum stability
3: near "DEPTH" pot right small : Nulling LFO depth F2 set to hi reso and listen for maximum stability
4: near "PAR/SER" pot : OUT1 VCA offset, set to mid freq and reso, plug an lfo or low osciallator source to AM IN and listen for minimal bleed thru
5: near "BYP/EFF" pot : Main out VCA offset, set to mid freq and reso, plug an lfo signal to AM in and listen for minimal bleed thru
6: near "RESO 1" pot small : treshold frequency for clock audio suppressors : those are extra low pass filters that are active below a fixed cutoff frequency,
typically 100 Hz center frequency, but to adjust to the taste of the user (not in V1 snr >1040)
7: near Filter1 "-B/-B+LH" pot : Bottom freq F1 pin 11 LTC1060 to around 1000 Hz
this means Freq 1 on minimum and all modulations neutral/off and no MIDI connected
