I didn’t. I’m not super versed in these. I have gotten very lucky over the years mostly with aa5 ‘s and with a philco chairside that I picked up. I have been replacing caps and cords and checking tubes but beyond that I have been kind of at a loss. I traced the three wires coming out of the output transformer and everything read open no continuity between any of the wires. I’m trying to learn more on each of these I work on. Can you point out the spot I should check my b+ voltage at? And maybe what it should be.

Also if the transformer just went out due to age can I use this p-t291 from amplified parts? I saw it recommended on a post about a 41-280. Not sure exactly how to wire it in.
