After replacing a burned out 71A tube I was getting one strong channel but no volume control. I figured I'd recap it and see what I got. While waiting for the new caps to arrive I went through the chassis more thoroughly and found that the output choke was taken out of the circuit with the speaker connected directly to the 71A and worse, the 2 AF transformers (#3077) appear to be open... I doubt I'll be able to find replacements and I don't want to put a lot of money into it. Is it possible to rewind these myself or use some modern replacements?
