Vintage Peavey PA-120 Transistor PA amp

I have a PA-120 four-channel mixer amp in for repairs.

This is a very early SS unit from Peavey.

It is in mint condition and all works except the power amp driver transformer has a open primary winding.

This is the old circuit where a split winding transformer drives the two or four output transistors.

VOX Thomas Organ amps and a few others used the same circuit.

The owner would like to sell the mixer amp, or if possible to find a driver transformer from another amp? then I will repair this unit.

The preamp stages easy to modify for much better audio quality.

I have a PDF I can Email.

We would like $100.00, or best offer.

Any help most Gracias,

It's a big country. Click on User CP, edit your profile to show your location at least down to county and state. On an inexpensive item like this, $35 shipping would be a real barrier.
