Hi Jim
You need to clean the contacts on all of the pushbuttons, as well as the contacts on the band switch. Deoxit is great for this. I tried CRC QD Contact Cleaner on my 40-155 (nearly identical chassis to your set) and it didn't work; the band switch and pushbuttons remained intermittent. After a dose of Deoxit, though, everything is fine; all pushbuttons now work as intended as does the band switch. All three bands are alive and work fine.
These are actually pretty good performers; they get their bad reputation from the rubber insulation used on the wires. Once you replace the old rubber as well as all of the paper capacitors and off-tolerance resistors, though, you have a really good, sensitive radio.
