>are there any"you tubes" or links that show how the IF transformers are disassembled?
I don't know of any off hand. The basics are remove grid cap, mark and unsolder the 5 wires that are on the underside. Remove the screw that hold the transformer bracket to the chassis. Carefully pull the transformer out thru the bottom. The coils and such are covered by a piece of fish paper, remove that and your in business.
That's plan A plan B is remove the grid caps from the ant transformer and the if transformer. Drill out the three rivets that hold the three covers on to the chassis. Lift the three cover off, the three of them are welded together so you can't just remove one. When reinstalling replace rivets w/6-32 machine screws and nuts and replace grid wire w/longer wires to make it easy to feed the wires up thru the covers while apart then cut to proper length when it's back together.
It probably goes without saying be careful when working on the IF transformer. It has several small wires from the coils that can easily broken. When replacing the 4m resistor just cut it out and solder in the replacement don't try to unsolder it.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
