Hi, I found this amp in a barn at my friends summerhouse yesterday. I believe it´s from 1965. Is this the model called Blackface? Is it supposed to be used both as a guitar and a bass amp? Does somone know how many ohms the cabinet is? I believe it´s two 12" speakers. I have never owned a tube amp and this one doesn´t make a sound, yet The speakers works when connected to another amp. When i turn on the power-switch, the lightbulb on the front shines bright red and a humming noise comes from the back of the amp. Talkbass can be one of the number one info sources for this kind of stuff. So if you know anything about this amp please tell me. To someone with tube knowledge. Is the black spot on the big tubes a sign of something bad? And as far as I know these tubes can be stock. Do they look like stock? Is this a good amp? Is it worth spending money on a service man? And do someone know what it might cost? I apologize for any bad spelling? Thanks in advance.
