Thanks, guys.

462ron, the 86.6 ohm resistor was chosen because it is the closest thing to 86 ohms that Mouser Electronics had in stock.

Now...

I spent almost the entire day with the 6-S-128 chassis.

First, I needed to determine how the 1st IF transformer was hooked up under the chassis and determine wire colors. (I had erroneously called it the 2nd IF transformer in post #32 above which I have since corrected.)

I made this partial schematic to help me:

   

Next up: Getting the 6-S-254 chassis out of the garage and onto my workbench to remove its 1st IF transformer.

   

A look under its chassis:

   

Finally, before I completely disconnected and removed the 1st IF transformer from the 6-S-128, I took this photo to remind myself how it hooked up under the chassis.
