Hello All and thanks Doug for responding, This PM I pulled the circuit board and done some pliminary checks. The power switch is working OK and the the transformer is steping down to 12.6 voltd AC. That is what I am looking for. AS this is an AC/DC set I will pick up eight “C” Batterirs and first check the set out on DC power. If the set then works, this should be telling me that the problem is in the 120 AC portion of the circuit. With the transformer doing what it was designed to do, for now I am thinking that the problem lies with a faulty 1N5401 Diode, which I will attempt to check out tomorrow. Should I not have any luck testing the diodes, and as they are cheap I will replace them all. I will keep you posted on my progress. I am also setting up my camera should I need to post some pics.
Regards
Ralph
