[NJARC] Power Supply Question

[njarc@mailman.qth.net]

Hello and Happy New Year to all.

       Thank you to everyone who helped me a few months ago with the Sparton 
Console Model 15 that I am working on.  Well, so far, I've recapped it, 
replaced the power resistor and have a working radio.  It has very impressive 
reception without an antenna and excellent with an antenna.  
       The only problem I have with the radio is the constant 120 cycle hum.  
I've tried to localize the problem by trying another speaker and substituting 
capicators.  No change there.  So what I've narrowed it down to is the power 
transformer.  I'd like to know if someone can help me make the final 
diagnosis and if I do need a new transformer, which one to get.   Is it 
possible to get the original rewound?   Should I be checking it without tubes 
and powered?  With tubes and powered?  I'll bring the radio to the next 
meeting so it can be tested.   
       For a quick reference the transformer has outputs for 2.5, 300, and 5 
volts.  It has 5 taps on each side.   

Thanks in advance for your help.
Joe
