Here is a link to Newark Electronics who sells replacements for the Vactrol LDR/Opto-isolators used in the 75 & 150 series amps. These would probably would work in the RP series as well.

LDRs for RP100 and RP65 Phasor

I’d like to revive this thread. I’m looking for LDRs for a RP100. These are listed as “VTL504” on the schematic. I can find absolutely nothing about them. It looks like VTL5C LDRs for the HD150 are available from many sources. The HD150 schemetic lists these as “VTL5C” but there are VTL5C1-5C4 versions of this. Does anybody know which one in the best replacement? Would these actually work in the RP100? Ewan
