Tube amp for my car

[mstaton]

Cadillacs DID NOT come with reverb units. They had the standard AM signal seeking radio. AM/FM mono was optional by '63 and did not have the signal seeking feature. They were tube with solid state outputs(hybrid). As far as that Fisher is concerned, you will most likely need to replace the electrolytics. They dry up and short. More than likely will have very dirty tube sockets. I've worked on tons of Fishers and they always have some issues. I suggest that you install brand new 7591's.
