Kenwood KR-8050 Receiver Repair And Restoration

This Kenwood KR-8050 in fairly nice cosmetic condition but the unit needs some repairs and restoration.

The top cover is off. The lay out of this Kenwood KR-8050 is neat and well thought out.

The faceplate has been removed to clean both it and the chassis side. Most likely never been off sense it was built in the late 70's. 

Warm water, dish soap, toothbrush, and rags go a long way to getting the year's of dirt off.

Q-tips also easily and safely removed grime from the tight areas. 

Using a lint free cloth is a good way to get all of the lint from the surfaces when you are finished getting the heavy grim with cleaning clothes. 

The bottom cover of this Kenwood KR-8050 solid state receiver is removed for more dirt and dust removal.

This Kenwood KR-8050 needs the control pots and switches cleaned with deoxit which is always part of any vintage stereo repair or restoration. 

Removing the metal plate on the Kenwood KR-8050 receiver makes it much easier to get the deoxit where it needs to be. 

Another assembly is removed for easier access. Normally you have enough play in the cables to make removing the assembles fairly easy.  

Don't forget to clean the back panel including the speaker posts, RCA jacks, along with the antenna and ground terminals.

The top metal grill on this Kenwood receiver had something on it in several areas that soap and water wouldn't take off. 

I used a little alcohol and that took it off. Always test a small area before you use any chemical on your equipment.

 

The Kenwood KR-8050 receiver is somewhat back together. It's time for some bench testing.

This Kenwood KR-8050 solid state receiver seems fine on the bench. Easily meeting specs for power and distortion. 

This Kenwood KR-8050 receiver repair and restoration is complete. It's time for some music.
