This will sound a little strange. I've got an old bass amp at my mother's house that I'm planning to take to my home. It's been there since 1980 when I left it there. And seems to still be in working order. It's a Univox, I'm unsure of the model (since I haven't been able to get a look at it in quite a while) but it looks like the drawing I'm attaching, which is labeled as a 1050. I've checked the internet (where I found the drawing) and searched for U-1011 Univox here, but haven't found much detail. Does anyone have much info on these old Univox amps?
