I have a Pioneer QX-747 that works good and sounds great except for the phono section. Aux, Tape, FM, AM all sounds great and clean. Set the unit to phono and I experience intermittent and variable, what I can only describe as "thumps" in the audio. These quite noisy episodes also show on the quad display in any or all channels and at various times. The frequency and duration of these noise episodes do seem to get worse in time.
So, with this, I assume this is in the phono preamp section however, it is not clear where the phono preamp is in this unit. It seems to be incorporated into the "EQ Amp" section but I'm not sure. Has anyone else had this problem? Got any suggestions in troubleshooting this?
Regards,
