Single channel AB763 build

[upnorth2]

Hello,

New to the forum and started building/fixing tube amps about a year ago at age 53. (No, that's not too old) Just need to ask something as I learn to navigate this forum. I'd like to build a single channel AB763, Deluxe or Vibroverb, eliminating channel 1. I should be able to mod a Princeton Reverb chassis I think. It seems pretty straight forward, removing channel 1 from the schem. and layout, including the 220K (X), V6 - pin 2. My question is about the 820 ohm resistor, V2 - pin 8. Need to change this? Any others?  Sorry if my circuit savvy is limited.

Thanks for any input.

Yes. Change to 1500Ω.

Welcome,

There is a goldmine of information here as well as a great parts source.

You may already have found this but if not the Tube Amp Schematic Library is a great resource:
