Anyone Recognize These?
« on: August 10, 2022, 03:02:31 pm »
During my research I believe I’ve been able to determined all of them were manufactured by Woodward Schumacher, but I can’t find much more. Any help would be greatly appreciated!!! Thanks all!!!

The Woodward Shumacher 606 P-6417 is a push pull output transformer for 7591 tubes, commonly used in organs.

Here's some offered for sale, with a claim of provenance.

The end-bell one...I'll take a wild guess based on another transformer I had a box of that started with 80-, and the other transformer in the photos being associated with organs.

The 80-xxx-yyy ones I had came from Heathkit, but they were not Heath-style part numbers. Turns out they were for Thomas organs. Heathkit sold some Thomas kit-form organs long ago. I think they were solid state. The transformers were about 45 Vac at 2A DC (rectified,filtered). I found a later rev. of them on a service site that had Thomas parts. I said 80-xxx-yyy because I don't think I have them anymore.

I could be barking up the wrong transformer...

Thanks guys, much appreciated!!!! I was pretty sure they were organ salvage’s. I bought a bunch of randos from a gentleman who was late in life and clearing out the stuff he’d never use. They all got shelved until I felt more confident about trying to determine how to put circuits together. Y’all are the best!!!
