HP Twin Output Transformer

Post by pimpstick »

Are you, or do you know someone who is an expert at identifying a vintage high power tweed twin output transformer? The amp should have an ink stamped 45268 with that really wide stack. This one that I have has a fender stamped schumacher 022889 EIA606-813, on the end bells, wide stack. Every pic I find of an 022889 is of the small stack twin reverb size transformer from the late 60's. I've never seen a wide stack OT in anything other than the vintage 5F8, 6G8, twins, and 6G14 showman. This one is stumping everybody.

There seems to be no hard cut off when Fender switched from Triad units to Schumacher in those amps .
The thing to do is to confirm that it's wound as a 4 output tube OT that wants a 4 ohm load.

The dimensions of the OT say it's the correct part, but I can't find any reference for those part numbers being from 58' or 68'. It is a 4ohm OT.
