I unearthed some transformers in some equipment I had gathering dust. There is a power and output transformer from a '60s tube mono reel to reel tape deck, and also one from a FM tuner. I like the idea of repurposing them, assuming they work, but have no idea if they would be useful in a Micro Champ, for instance, or another low watt guitar amp. The tape deck has 4 tubes: 6AQ5A 12AU7 12AX7A and 6ME5 "Magic Eye" I don't know if that's meaningful information, but am curious if anyone has ideas about utilizing any of this stuff for a fun build. I don't have any amp building experience at this point, so the point may be moot! Here's some pics. The first is from the tuner, the other 2 are from the tape deck. Thanks for looking!
