Value of the Yamaha CR-220
During its first year Yamaha offered this receiver for around $240, which positioned the CR-220 slightly above most other intermediate class receivers. The CR-220 has 15 Watts per channel at 4 ohms, which is lower than some other receivers one could find for the price. However, the CR-220 receiver has commonly astonished listeners by its clear sound and outstanding performance and can compete with most modern receivers in its class.
Yamaha CR-220 Repairs and Care

Another typical issue for many receivers of this age is oxidation. Metal connectors oxidize over time, which reduces their electric conductivity. One will hear this by loud, scratchy noises. To help with this issue, simply use a deoxidant, such as DeOxit, and apply it carefully on the typical spots, but never on relays! If you are wondering what the typical spots are, you should google for a DeOxit guide that teaches you how to use it on your receiver. In particular potentiometers (pots), switches, RCA and all socket contacts can usually benefit from some DeOxit spray.
In case you simply want to do something good for your CR-220 you can solidify its ground path, which can work wonders. Simply unplug the receiver and unscrew the bottom cover. After you removed the cover, you can see the screws that hold the circuit board to the heatsink rail. Unscrew those screws, take off any oxidation and shine them up. You can use a small grit file to do so. Afterwards reinstall them, using toothed lockwashers. At last you should open the top of the receiver and tighten all screws that connect the heatsink rail with the chassis. You can read more about this method here.
