Replacing what I believe is the AVC cap for the 24A IF tube and the caps in the #30 box seem to have jus about taken care of the volume issue. The radio is now almost silent with the volume turn all the way down. AVC action is working better too. All the strong, local stations are about the same volume as I tune around the dial.
One metal box and two bakelite blocks remain to be rebuilt. Then a few of resistors need to be replaced and it's alignment time.
I am also pursuing the speaker Dick mentioned above. The cone looks very good but it is missing the output transformer.
I'll get a Hammond 125 SE series transformer if I need to.
Am I correct in thinking that a 5 watt output transformer would be sufficient for a single 47 ?
125BSE $54.79 at Mouser Electronics. Ouch!
