    I've been doing a restoration on a 2220, I upgraded the P-800 power supply, P-500 pre-amp and P-900 phono boards so far, anyway I'm no sure if I noticed this before but when I switch from phono to fm or from am to fm on selector switch I hear a loud click in the left channel only, you hear it even if the balance is all the way to the right channel and volume all the way down, phono to aux or aux to phono no problem only to fm. It's not a big deal but annoying. Has anyone noticed this one before, also you hear it through the headphones also in left channel only.

    I would start with a good Deoxit cleaning, multiple times while working the switch through it's various positions.

    Maybe there some DC on the line.

    Maybe the phono P900 amp is leaky. check the output of the p900.

    luck

    I did the Deoxit cleaning a few times and click is still there , strange it's only in left channel, could it be in the FM board I believe the P-200, maybe leaky caps?

    I restored the P-900 board over the weekend, changed (7) e-caps, (2) film caps and (2) 2SC458's transistors.

    Post a clear picture of the P900, perhaps something is amiss that someone will spot.

    I restored two 2220's, and if I remember well, on both of them there was a SMALL ticking sound on both channels when switching to FM. Just a small short "tick" sound, nothing that made me worry.
