spent the day with ex-NY producer buddy doing a full restoration on his 22-09-71 Marshall SL100 // B+ = 530vdc (plexi volts!) … I wired three-way Lorlin rotary switch for Ohms select on a copper plate mounted to cover previously discarded original line-voltage and ohm-speaker select switches … corrected some poor PSU mods, replaced missing signal caps in preamp with NOS Mullard’s from same era … one of the best sounding Marshalls I’ve ever played // 11 on scale of 1 to 10
