Title: power amp resources
Post by: mlhuff on October 22, 2020, 11:01:22 am

I am interested in building a power amp only, I will use a preamp. I am looking for help in design and build.
Any help is appreciated

Copy any amp you like, but chop off everything before the phase inverter.

Unless your desired amp uses a split-load inverter: then keep the 1 gain stage before the inverter (where the feedback loop connects) and cut off everything else.

It's really that simple.

What sensitivity are you aiming for?
