IIRC these contain quite a few Hunts 'Moldseal' capacitors (the ones with brown 'cases'), all of which, IMHO, should be replaced, along with any 'waxies' if present. In particular 'that' capacitor (often mentioned in this forum) MUST be replaced. I, personally, also replace the main reservoir and smoothing capacitors in any equipment of this vintage.

Another one to change is the electrolytic in the FM discriminator circuit. This is connected with its +ve terminal to chassis, and has a value of 2 or 4uF (use a 4.7uF). In all cases, the working voltage of the replacements should be equal to, or greater than, that of the originals.
