Title: 5F6A Layout to AB763 Spec (No Reverb & No Tremolo)?
Post by: jonyoungyi on November 29, 2016, 04:53:43 pm

Hi, I was wondering if it's possible to use the Hoffman 5F6A layout, but change the components to a AB763 Deluxe Reverb spec's.

I've built both the 1 Channel AB763 (Deluxe Reverb spec) and the 5F6A Bassman. They sound very different from one another.

I recently sold the AB763 and am missing it's sound. I would like the AB763 sound, but without the Reverb and without the Tremolo, as I will be adding them digitally via an effects loop.

The layouts are very similar, but there are a few components that are different and shifted to different locations, so not sure how to go about this.

I did manage to gut the reverb and tremolo from the hoffman AB763 layout. Looks ugly and not sure if I got everything, but dawned on me that the 5F6A layout looks similar.

What do you guys think?

I would just pull the 5F6A board and install the AB763 board.
