Title: Old Topic , Channel Switching
Post by: HighFlyingV on June 12, 2022, 09:45:25 pm
New post , first off. My original plan is the 6V6 Plexi/2204 designed as a plexi Normal Channel + Volume , 2204 in place of the Treble/Bright channel . Exception is Tube rectifier.
I would like to be able to use a foot switch to go between channels possibly beside that use the volumes to blend both channels. So 3 options.

Using Traditional 4 inputs would it be best to just use a A/B/Y or install an internal switch board ?

I have a lot of hard parts , Transformers ,Turret board , chassis.
Most the electronics on hand.

I thought that would be the best option. Once I finally figure out how to make it work.

I just thought internal switching would be nice but I don’t want a more complicated circuit.

You plug each one of the ABY outputs into one each of the amp’s input channels. And use the pedal to have either or both channels going. A Morley active ABY pedal would be suitable.

Oh yeah , I can do the A,Y,B I was referring to the layout schematic for the build. Figuring that out. I might just do the 2204 6V6 because I have most of it. The only big difference is I am using a tube rectifier. Fixed bias JJ cap can 20,20,20,40.

I had a chassis made to slide in to my Bugera V22 Head Cabinet.
