KEF in New Jersey is now the MF distributor in the US, you should try them. Rick Walker from Signal Path ( the old MF distributor) is a really nice guy and he may still handle MF Service as well although I don't know. If the transport is the problem you are out of luck but if if is a board or power supply issue you may be able to get it fixed. Look on Audio Asylum or the discussion forums here and you should be able to get Rick's phone number.
Good Luck
