Yeah, I suppose it sounded like a way cooler conversion than it actually was! One thing I DID do, however, was to add a rotary switch to change which pin of the OT connects to the negative feedback loop. At the expense of some volume I can get it squeeky clean (i.e., as it was supposed to be), or if I want I can get it to have some pretty nice breakup (i.e., so it can be used more like a regular guitar amp).
Believe it or not, I found that MPA20 head in the Goodwill on sale for $8. The only thing wrong with it was a blown fuse. Gotta love those kinds of thrift-store finds!
