Hi Jim,
I need to explain what the audio driver transformer post was all about. It's spiraling into space.
I'm working on a 1935 Stromberg Carlson 83 (a big 10 tube console). The primary of the audio driver transformer, part 22803 is open. By the schematic it steps up from one 6F6 tube to a pair of 6F6s (2) in a push-pull output setup. Then there is an output transformer and so on. This is actually where I need the repair. Because I had a 1935 audio-transformer from a Philco 116 (step down it turns out) I thought I would ask the Philco Phorum what kind of wattage these carry, getting a ball-park for the Stromberg. I guess Murphy's plan kicked in quick.
The Stromberg trf does appear to be a step up, between two/three to one. Still the question is, will the 5w ones they sell on the market handle the heat? Is all of this clear as mud? Thanks Jim.
