I'm rebuilding a Model 80 (Philco Junior). The primary of the audio transformer measures ~4.4k; the schematic calls for 364 ohms. Obviously needs replacement.
I have a same physical size scrap transformer with a primary resistance of 210 ohms.

Can this transformer be used safely as a substitute? Should I expect lower power output? The output tube is a 42.

Thanks, Don
