5F6 phase inverter and cathode bias?

[Bluefinger]

Thanks a lot! That's exactly what I was planning to do.

Implementing reverb into a tweed circuit will be the next thing I try to do. I thought you need to put that reverb circuit across a much larger dropping resistor like the typical 3.3Meg in the Blackface amps to make it work propperly ... ok, maybe that should be dicussed in a separate thread ..

It's easy, look at this schematic (it's a 5F6A Bassman, but the reverb circuit works fine in my 5F4 with long tail PI). One exception: I left out the 1Meg pot before the reverb driver grid and put in a 1M resistor to ground instead. That way it's sort of a standard Fender reverb with just one 12AX7. I've used this circuit in 3 amps so far and it's got plenty of reverb IMHO.
The schematic is from tubenit. Another member of this forum.
