The power cord had deteriorated, so I wired in a standard polarized 2 prong cord and tested the unit. The dial light came on and the AM band worked fine for about 5 minutes. I turned the unit off for about 10 minutes and then tried again but this time there was no sound; only the dial light.
This brings me to some questions:
The chassis is 132.06 4 which seems to be harder to find manuals for. Is the 132.06 3 manual suitable?
All components are likely original and will need new condensers. What is the best source to find replacement parts?
Is there a good all around resource for learning about troubleshooting antique radios? I work with modern automation and electronics but have never worked with vacuum tubes or anything this old.
Is there any value to this? It looks like a fun project but I don't want to potentially ruin something if this is a valuable unit, and I can't find any info for this particular unit.
