Had this amp for a few years, with no problems, but over the last few months, when playing vinyl, and CDs, it's started 'pinking'. I.e. the sound cuts out for a millisecond, very intermittently. I've opened it up and used some electrical cleaner on the parts I can access. There was a fair amount of dust in there. Any thoughts? Thanks in advance.
