37-675 Bandswitch
#4

Hi Terry

You're right...that is a really nice radio! Looks like it has a new Mark Oppat dial scale, too.

In order to get to the band switch wafers, you will not only have to remove the RF unit, but once it is out, you'll have to disassemble it as well, removing the antenna section (back) and the RF section (middle) to be able to see - and service - everything.

You have to pull the shaft out before attempting to remove any of the sections of the RF unit. It is held on in front of the unit with two small bolts on a flange. Note that the shaft is indexed, so that it can be inserted only one way without damaging the wafer sections.

Removing and disassembling the RF unit is not as difficult as it sounds, but is definitely not an easy job.

For what it's worth, I once had a 37-something Philco that would not work. The problem turned out to be an arcing wafer switch section. I managed to cut away the burned part, and fill the crevice with epoxy. Worked fine afterwards. I was, quite frankly, amazed that that sort of damage could be repaired.

Good luck.
