Effects loop for Hoffman Ab763 one channel

[KimboDb]

hello, I'm interested in the adding an effects loop to my amp. Is this feasible for my hoffman amp also, Is it a difficult add-on. The amp already built and has been used for a month now. If it is not to hard and doable, were would i start. Thanks ahead of time for the responds.

There are modular FX loops that are easy to add on.
Solid State.


If you have an extra tube, you can build a Dumble type FX loop with
a send and return level pos... if you so wish.


I built a Dumble out of a Bassman 70, and had the extra tube there to use.

Lots of things could be done.  Here is one idea.  Unity gain with equal signal at Send and Return.

Do you have the schematic for this

Here is a thread in ARCHIVES with numerous FX loop designs.  The dumblish ones are posts #13 and #14.
