Hi Ron --
That's good to know that the transformer is probably OK. The cap is non-polarized, and I'll have to check to see if it's the culprit when I get back from work tonight. One thing I just noticed is that the restorer swapped the leads from the transformer secondary, with the blue one going to cap 151 and ground and then to the tweeter pair, and the yellow-blue-tr going straight to the tweeter pair. I wonder if this would make a difference (I'm not sure of the purpose of the connection to ground in this circuit.) If so, then whoever had the radio before me never heard a thing out of the tweeters.
