Will you guys keep me updated on how this project goes? I have one 455 kHz
SB-620 that is kaput right now. I may end up buying another for repair and
parts. Also, there is one resistor up on the top that is IF dependent,
located on one of the CRT controls. Don't overlook that as the wrong one
will squish the display horizontally.
