The Fine Things are Always Hand Made
Thanks for the help on my scott philharmonic. got both tuning eye tubes working after alignment and replacing about 10 resistors and over 70 capacitors! what a job that was, took several days and a lot of soldering, but results were worth it. I need 14 chrome tube can caps in any condition, any ideas? now I am using zenith tube covers so as to align set . this is my third scott, two allwave 23 tubers and this 1940 philharmonic. I can not find a schematic that matches everything in this radio, any help appreciated, jimmie ashabraner
I thank you for the advise, I too have found cold solder joints, but not on this set, mostly capacitors that were old and shorted or out of tolerance. I have found that if you are working on a 50 year old radio, replace all the caps to get it back up to its original specs. I found several resistors very high in value, so they got replaced too.
the set plays very well, have ran it for 4 hours with no overheating or loss of sensitivity, am very pleased with it, especially the shadow tuning dial!!!
guess I was lucky there were no coils or transformers burned out, thanks, jimmie
Jimmie - With the Philharmonic especially, you probably won't locate a schematic that matches your set exactly. This is the hazard of "custom" radios vs. production line sets. When you find something that is not the same, sketch it into a photocopy of the schematic and see if it makes sense. Also, look closely at solder joints and the components to see if it appears original or altered. Once you do those things, then you can decide to repair as it sits, restore it to "original" or even modify, if you believe there is an error (several of us have found wiring errors over the years!).
