On my 1973 Minimoog, for oscillator 1 & 2, the first two waveforms (triangular and triangular sawtooth) the volume level is very low compared to the rest.
Osc. 3 seems to be ok, much more present and consistent levels over all 6 waveforms. I wasn't sure if there were independent adjustable resistors on the circuit boards to calibrate, or if there is a method of increasing the levels of each waveform. Any advice would be appreciated! Thanks
