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.Newark Electronics: VTL5C |

Hi Erwan,
I know it's a really old question but those VTL504 may just be a MM nickname for VTL5c4/2 (they have 5 PINs like the one we have in our beloved RP100 / RP65, and the schematics would fit too... It's just a question of value then) and the name is close enough. Note that I may unsolder the one in my RP65 in the next months and try to see if the reference is on the back of the component.

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
