Hi all,
recently I discovered one problem with my Pioneer receiver SX 9930. When any other appliance (CD player, tape recorder, even washing machine etc....) is turned on or off via mains switch, I hear loud click in speakers. Sometimes even speaker protection is triggered.
Did any of you had similar problem, and what could be done to eliminate those clicks?
Thank you all,
Ivo

Did you change anything in your system - e.g. new cables, moved a piece of equipment or your system? did you change to a diffrent mains socket?
the Pioneer is over 6months old.
According to the Pioneer advertisements it has been superceded by thirty newer and better models.
Bin it and buy a proper amp and tuner.

Actually, it is over 30 years old, manufactured in 1976🙂 Model for different market (non European) was SX 939.
What was changed in my system was speaker cables and AC outlet. I allready did plug back receiver at 'old' AC outlet, but effect is still present. Clicking is present when receiver works alone, with or without RCA cables plugged in inputs and it doesn't matter if I chenge position of mains cable in socket of any unit (changing phase and '0'). So I eliminated moving and changing mains socket as possible problem.
I was thinking on some kind of mains filter but I would like to know did anybody else have similar problem and what was possible solutions.

You might try adding a capacitor across each secondary winding of the power transformer. Start with .1uf. The voltage rating of the capacitors should be 3 or 4X the voltage of the transformer winding.
The capacitors will absorb the spike.
