Hi Mike,
I thought there might be a better way. But too late for me now. I have already removed and replaced the sub-chassis. Many of the interconnecting wires needed replacement anyway. (That's what I am telling myself, anyway.) It really wasn't that bad, to be honest. I just marked every lead and noted where they were connected. The only hiccup was that I missed one lead location on my location map. I still think removing the sub-chassis was a good option. Removing it takes the stress off the leads when manipulating the chassis. Especially when trying to get to those two caps buried inside the band switch.
Long story short; I powered it up last night. It all appears to be working, on the BC band, anyway. I still have more to do, but at least it is working.
One of the more difficult areas, I thought, was in the audio section, immediately behind the sub-chassis, on the main chassis. Getting to and replacing some of those caps and resistors was somewhat difficult. I found one resistor in the volume control circuit (as I recall) that I couldn't find on the schematic, parts locator, or parts list. It was a 2 meg, and appeared to be factory installed. Since it was within spec I decided not to replace it and left in place. I need to go thru the change list and see if it is mentioned there.
All in all, I am just pleased that it is what appears to be working normally. The AFC is even working.
Thanks again.
