A Philco 38-690 Restoration
#10

March 24.

I begin work on the tuner chassis by removing the RF unit and setting that aside, and then tackling the IF - expander assembly. The wires protruding from the top of these cans and going to the IF amplifier tubes were badly frayed and in need of replacement.

Here's how those IF transformers look with their shields removed:

After replacement of the wires, the shield was put back in place.

I find it easiest in these situations to feed the wire (in this case, wires, plural) from the spool of wire (again, three spools in this case) through the shield, solder the wires to their proper place(s), reinstall the shield, then cut the wires to the proper length. This cuts down (pun unintended) on wasted wire.
