Sweet find:yes: Congratulations David. Those 6hu8 tubes are kinda pricey, $40.00 and up for a single tube but they sound very nice. I have them in my Fisher and they sound great. Are all the tubes Fisher branded? The 6hu8's and the 12ax7's could very well be Telefunkin's with a fisher name. Found out thats whats inside mine after a friend told me to look for the diamond shape in the base. It should sound fantastic after doing a recap.
Audiodon, yours was a 1964 Philharmonic IV with the 290-T Chassis vs. the 1965 and 1966 Philharmonics with the 29-T chassis. Very similar but there are differences - I will post the tube layouts of each in the Fisher Consoles sticky for comparison purposes. I do have the owner's manual for the 1964 Philharmonic IV which is probably nearly identical to the 1965 and 1966 Philharmonic manuals. PM me with an email address if you'd like a scan. No schematics, though.Mine's long gone. Can't help with paperwork. I never saw a schematic, though I think it had the tube diagram on the back. If there was paperwork, perhaps TheRed1 has it.
Well, an update....
It's in daily use with all original components. No problems at all. Someday I might drop a Dual 1218 or Garrard Zero 92 in it.
