Hi, have a Yamaha CR-220. When you turn it on, plays fine. But, within a few seconds fades out to static. Turn it off, then turn it back on-same thing. I am thinking power caps? Already reflowed a few iffy transistor solder joints. Bought all 4 transistors to install IF that may be the issue. Can anyone point a newbie to some areas to explore?
Found the screws on the transistor bar were loose. Tightened them and now get continuous sound but distorted and staticy. A while back a friend who is a tach put two pieces of thin cardboard under the transistor bar. That worked for a while. I resoldered all the transistors.
Also cleaned all the pots and switches with DeOxit.
Sound only on mono not stereo. Meter working. Transistors 2 and 4 have no reading on the multimeter.
Thanks for any help.
