help me with this.............

There could be an issue with the pv 12 selector switch that you use to go from tuner to CD, then back to tuner.  It could just need its contacts cleaned or if it has been used a lot over years, the selector contact could have developed a flat spot from wear.  If that's the case you would be looking at having the selector switch replaced. To diagnose the issue, try working the selector switch and see if you hear the static as you toggle from one source to another. Again...this is a possibility not in any way a certainty.

you may be right. another thing I have notice is when i play my tv thru the stereo, i can still hear the tv sound though faint .....when I change to another source.

Hearing another source that’s still on isn’t that uncommon.

On the other issue i agree that it’s most likely a dirty input selector, my suggestion would be until you can have all the controls cleaned and lubed exercise them a bit. By this I mean, turn the amp off so no transient thumps, then work all of the controls several dozen times each. For example, rotate the balance knob clockwise then counterclockwise back and forth rapidly over and over. This will wipe away most any tarnish that may have built up on the contacts and usually alleviates most issues,for a time. This in no way replaces a good cleaning, but should help temporarily.
