George,

The website posted will get you on your way with the 2nd converter chassis.  I did not read it in detail, but make sure your MARK EVERY WIRE you take out, especially the coax wires, so you can get them back in the right spots.

In reviewing my notes on the radio I discovered posts from a fellow who had “peaked the 50.5 kc IF by ear”. DO NOT DO THIS.  You either need an accurate signal generator, or a stable one with a frequency counter, or a swept oscillator with good marker generators to do that alignment.  It’s best to just leave the thing alone.
