I just repaired two of these tuners today

 

C5 in the power supply is the problem with these tuners.  This is the capacitor for the relay power supply which is a 22uF.

 

First, the tuner will have intermittent problem with the muting in on position,  After, the relay will buzz and will break with time.

 

Changing C5 and sometimes the relay are easy.  You can place a small plastic relay inside the faulty metal one .
