Rich,
All MM's have a solid state pre-amp. If it's a good deal, grab it. If you don't, tell me how I can find out more. I might want it!!

I got the message from host Steve Kennedy and he says he can see the tube in the pre amp as it should be in the early 70's model. It was late in the 70's when they went to solid state pre amps. thanks for the reply

Sorry, read his message again. All Music Man amps are solid state Pre-amps. Every one.
