Philco Seventeener II

OK, I've got the IF strip aligned. Now onto the 4.5MC trap adjustment. For this adjustment, they require a test "set up" or test detector. It requires a 4.5MC adjustable trap and some caps, resistor, and diode. Here are the pictures of the procedure and the test detector from Sams. Same thing in Riders.





Anybody have any tips on how to do this without the test detector? I don't have a 4.5MC adjustable coil. Unless I can pull one from a spare chassis?

I found a 4.5MC trap on an old Motorola TS-89 chassis and it worked out well.

Looks like you're coming along fine.

Thanks Bill.

I finished with the 4.5MC and audio alignment.
I installed the back and all that's left is to do is refurb the top knobs.

BEAUTIFUL! How did you de-yellow the back so well?
