Park 45-Watt This is the second Park amp I owned. I bought it shortly after selling my baseball card collection in 1991. I think one of the transformers was rewound or replaced in the '60's (with a similar one) It is marked "bass" on the back in gold ink. It is still my favorite amp and went on tour with Captain Crunch. It is supposed to have these white "banana" knobs like the top mount amp so I put them in with Photoshop! BACK
