Last year I rescued a Fender 75 from the dump. It has busted on/off , standby, 75/25 switches and no foot switch. I took the chassis out and tested the 15" speaker and it sounded great through a friends Valve Jr. I'm not great with amp repair so it just sits in my closet apart until I can figure out what to do with this behemoth. I use a couple of Pro Jr's that weigh in at 20 LBS. I don't want to give it up because it's hand wired and has a massive reverb can and all the tubes are intact. Anyhow I have one that isn't useable at the moment.
