I have a k7200 that when i plug in it gives a high pitch squeal, like a dog whistle, and a sound almost like static. there is no picture or neck glow either. I put another chassis on the tube and it worked great. Just want to know where i should start looking. thanks
 
where i would start is center all of the pots on the remote board.
they may be out of adjustment enough it is stressing out the chassis.
i have seen this happen.

after that i would start with a full cap out. not a partial kit.
i have never liked the caps wells used and do not trust them.

this is where i would start.

Thanks for the input, i will adjust all the remote pots tomorrow and post my findings. As for the caps, is Bob Roberts the best place to get the cap kits? Oh and how do i tell which K7200 model this is? i read somewhere that there was 2 made, an A and B version i think.
 
well after playing with the pots with no luck, i started to do some aggressive negotiations with the flyback adjustments and i got a picture and a change in the high pitch tone. The problem was the flyback all along, but i still need to replace it because it still cuts out and squeals off and on. Buffett graciously volunteered to do an inventory of all the caps and make a kit for this for other members who come across any problems with this K7203 chassis. Hope this post helps someone else, i learned a little myself.
