Ok here is where it gets a little weird. There is no label with a serial #. The serial # is stamped on the rear of the chasis. SS8986. I'm doing this all from my phone. I will post pictures tomorrow.
When were the studio 22's first put in production? Ive got a 3/88 on the chassis. Does that sound right? I want to replace the tubes. Any suggestions? Many more questions but I don't want to be a bother. Just excited!!!!!!!!
