Need push pull driver transformer for SS amp

ElectricMan · 11th August 2010, 03:02 AM

Hi

I do repairs on all sorts of "Stuff", mostly early tube gear

I have a old Peavy SS amp, a PA-120, four channel mixer amp.

It is mint, inside and out.

The driver transformer primary is open, need another.

I could take off a junk amp, about a 50-100 watter amp.

Same as old Vox also.

Any help Thanx a bunch

I found the schematic here: http://www.peavey.com/media/pdf/manuals/pa120.pdf and not much info on the driver transformer, other than its Peavy p/n "DG 298". I'd try Peavy for the part. It has low-Z secondaries to drive the output transistors, which makes it harder to find.
Otherwise, Sowter transformers has some good British steel and a vintage clone service they provide.

Open the transformer carefully.
Small cable transformer most forced at near terminals and broken if not burned.
