Technics SU-A900Mk2

New on this forum!

I have a full Technics stack (bought in 1999) and has worked perfectly fine for years, however, I now seem to have a problem with the phono.

All the rest (CD, MD, Tuner, Aux etc) all work fine, but have a static hum when amp is set to phono even if the deck is not powered on and the banana leads are disconnected.

This seems to point to the phono stage internals.

Is this something the could be repaired? If so, any idea how much would that cost (am in UK)?

Or is it worth me buying a used serviced model from a reputable dealer or P/Xing the existing one for a replacement?

thanks
