Vintage Synth Repair

>>A client of mine has a CS30 with a dead LFO chip.....unobtainable<<

you sure? I bought bits for my cs30 through yamaha kemble in the uk quite recently.

in any case, look at the schemos & decide if you can be bothered to work in an equivalent of some sort. it's a VC-LFO &, from memory, feeds a wave-shaper chip & thence the modulation buss.

if you get stuck (for the schemos), let me know.
