These are an amazing set of amps made in the 70s. They sound warm and totally natural. I only use musical sounding components and these are very musical. The huge transformers contribute greatly to their wonderful sound. Overall they are in very good shape for their age. The name plate on one of them broke, i glued it and it came unglued. I can re glue it if the buyer would like or I can leave it to them. Another great feature is they have volume knobs eliminating the need for a pre amp. However I think any amps will sound better with a pre. To get a better sounding set of amps you will have to spend significantly more than my asking price.
