    Beautiful, looking at buying one of these myself. Did you only replace the Electrolytic capacitors and what did you use? Was thinking of using Nichicon fine gold as they're pretty easy to get hold of here and also doing a small mod to by-pass the caps on the 100pf load for the phono cartridge as my cart requires a very low load where the capacitance in the phono cable will be enough.

      Hi! This had trouble with switch and input selector , sometimes sound dissapear on 1 channel , phone selector and tone bypass were dirt.
      Also fully recapped , nich FG are Hq caps and they can be right choice .I used to use Nich , vishay , spraugue choice from best series . Yes , you can lift off 100pf , but I 'll put a little 22/33pf to avoid HF noise .

      This pre is also stress from reverse pcb mounting .
      The solder are on the top and voltage regulator are very hot .
      I suggest to correct the solder all over the board
