Issue with rebuilt 38-690 audio transformer
#13

Huh. That's too bad; thanks for that info though. 
Replaced all the electrolytics, checked tubes etc and brought it up for the first time today .... Deadsville. Not a peep out of the speakers. I was hoping it would be something simple like a blown fuse in the AOT, but no such luck.
This radio came to me with two blown 6L6 tubes and that open interstage transformer, which was replaced by Heyboer (see posts above) and re-installed. The power supply chassis has been recapped, and the five-section lytic in the receiver section has also been replaced. All the tube heaters are lit; getting 300-sometthing volts in the 6L6's, but the other two tubes in the power supply (6F6 and 6J5) are giving odd readings, not much voltage going through them.
I'll continue checking the loads on the tubes for now, and double checking my work. We shall see Icon_smile


Any other suggestions?
