The Fisher PR6 Phono Preamp Circa ’55

Been working on developing a ‘NEW’ octal -based RIAA preamp so this caught my eye in a giant pile of rotten paper at ye olde Sunday Flea.   Click the link below to download the manual for the Fisher PR6 preamp, including schematics ETC.  And check out this link for some worthy thoughts on mod’ing the circuit.

  • Is this a 6SC7? it looks like both sections share a common grounded cathode. I suspect this is the same as the GE UPX-003 Phono preamplifier.
