Re: RCA AR88D Comms Receiver.
Bearing in mind the age of the AR88 there could be dozens of minor problems all conspiring to defeat the repairer. It's ages since I last overhauled one of these (I have 4 at last count but they're so heavy and cumbersome to work on they're not very inviting). I'd recommend removing the capacitor C119 at the anode of the audio output valve because when this fails it can open circuit the primary winding of the output transformer.
