[70cst]

My opus 7 is starting to "hum" which I assume its due to bad filter caps or a transformer going bad. Sounds like a 60 cycle hum. I would like to have it gone through so the question is" are there shops/persons who do this kind of work? I travel through out Oh, In, Ky, and some parts of Tn., and Mi. I really do not want to ship it. Thanks in advance.
