Philco model 42-1012 power problem

As long as you can determine the primary winding, colored wire won't matter. Connect primary to source, and measure voltages on secondary leads.

Filament windings will have very low resistance across it. The secondary will have three leads. The other "should" be the primary. The primary will have higher resistance across it, than the filament windings.

Measure resistance across each winding in your transformer. Based on what you're saying, it sounds like all of the secondary windings are open. That's not impossible - but it's not likely.


You lost me Greg,
Have not run any of those tests before.
I just check for voltage with my volt meter,and am not getting anything from the output side of the tranny.
Not sure if this could be due to a problem with the switches?
They seem to operating as they should mechanically?
Thanks again for you help.This is kind of new to me.Just a hobby at this point.

Would the primary be from the chassis strip wher the cord is connected to the wire that goes from the chassis strip to the tranny?
I am really new to this.Played around with old radios when I was a kid.Now I am 60 and have found it to be really enjoyable to bring these old radios back to life.
So excuse my ignorance,but I am willing to learn.
Have a great weekend

Thanks Morzh. So it appears I did wire it incorrectly and I have to switch the wires between pins 2 and 4.bobclausen — 09:24 AM

No, it's not a problem, just during certain condition it could show up. Yes, an internal tube short could do that too. ...morzh — 09:13 AM
