Default Amp making phase shifter noise

I have a Mesa dc10 that in the last two days has started making a phase shifting noise. I have only noticed it in the overdrive channel. The noise comes and goes at random. Any ideas as to what is causing this?

i would guess RF interfiernce and/or oscilation in the amp. its possible that a filter cap has gone bad, but first thing to do is try a tube swap and re bias.
