Philco 60 code 121 IF's
#19

I'm not a chassis hacker upper. The repairs I do I try to make look like they are period correct. I would take out the old IF transformer and mark the wires, it may come in handy later.

Philco made a billion of the model 60's from '33 to '36. I'd say it's one of the most asked about sets on the forums. The later sets may have the trimmers incorporated with the coils in the can so this would require some fab work to use those in the stock early setup. Seems like it shouldn't be too hard to find a parts set.

Or maybe use a Ktran transformer, that's one of those 3/4"x 3/4"x 3" tall 455kc IF jobs that were used in the '50s. Solder a tab onto the brass clip that holds it in place and stick it in the can where your bad one was. Use the tab as a bracket to screw it down to the chassis with. This is after aligning it to 460kc. 

I'll mention in passing that 1st and 2nd IF xformers are not the same and don't make good substitutes for each other. The 2dary windings different impedance's. 1st IF is high as it's designed to match the control grid of the IF amp tube. But the 2nd IF is low as it's designed to match the diode load of the detector. You get better performance by using the the proper transformer as in was designed for.

On the sw check the osc for a signal at 460kc above the dial setting w/your counter. You may find that the trimmers for the sw band are so out of alignment  that the osc has quit. So it could be something simple that doesn't make your hair smoke!

figure out what all those squiggly meant.
