Another Hoffman PR Build
« on: April 02, 2020, 08:05:50 am »
Hey Guys/Gals

If you are thinking of building a Hoffman PR I'm here to tell you to go for it.  They are fun projects and the bonus is at the end you have a GREAT amp, one of my favorites.  I build lots of these and you should too.

The one in this pic needs filament wires and an AC cord and she will be ready to fire up.

A few changes I do:  DR OT, .022, .022, .01 in the trem circuit as well as replace the 1M with a 220K.

tip for first timers: wire the board first which will save you much grief :)

Cheers
Mike
