Fisher x100-3 power transformer

[CORYK]

What should the a/c voltage measurement be on the secondary outputs of the power tranformer on an fisher x100-3 with 105-117 v primary input? This would be on the rectifier winding side. Thank you for any assistance.

Craig? Any ideas? Thanks!

If you're having trouble powering the filaments to the tubes, there are a couple of resistors in there that you can change the values on to boost the voltage, particularly to the preamp tubes. I can't recall the positions without the unit in front of me, but if you have a schematic, one of them is right near the filament listings on the schematic. If you remove it, the only consequence is that you lose the ability to keep a load on the circuit if you pull a preamp tube while the unit's running. You'd pop the fuse. That's how mine's set up now.

Did I understand your question correctly?
I wonder because I answered what I see as the primary problem with these, and it may not be what you're asking. I guess I inferred.

Don, The filiment supply seems fine 6.7 volts. Its the other secondary winding I was inquiring about.
