1963 Bandmaster (finally a round tuit)

[Reeltarded]

Added a node for normal channel stages, changed normal channel stages to .68 bypass over 1k5, normal channel tone to 47k/470p, .022 coupler to 270k right onto vibrato channel input grid. Added IM master in ground flip whole.

It sounds like Stevie Ray Vaughn being thrown off a mountain my Jimi Hendrix and landing on Robin Trower.

Didn't leo implement a back panel control to tweak the phase shift vibrato that he ended up not using?

I seem to remember that some early Brownface Amps had this hole on the back panel that ended up not being used.

Please tell me more about the control Leo didn't implement?

Could someone please draw up a circuit of the amp thus far?

Is this amp the 6G7 or the 6G7a?

It would be easier to read than text.

I recall reading the same thing at some point, and seeing a photo of the mysterious unused rear-chassis hole. The conclusion was that the extra control probably wasn't very useful.

Nice sounding tones!

Miles !!! So good to see you here again. Hope you are well man. The clip sounds bitchin. Great mod

Heya, John! Good to see you as well!

My center volume bandmaster has the plugged hole for the never implemented trem bias whatsitz. I can verify that it's completely useless.

It's a hole.. with a chrome plated plug in it.

If I were to hazard a guess I would say the missing pot would be a 2M lin pot in place of the two 1M resistors that act as grid leak resistors on triode which feeds the PI stage.
