#87 on the schematic.
This radio had a 8" Zenith speaker attached to it when I got it. I do don't know the history of the radio, but it was a terrible mess. Mice had eaten some of the
caps and everything paper and felt. Even the dial cord! This radio had been used as a mice condo for years, and stank to high heaven! There was a large mitten on top of the chassis and inside the chassis. I know this is common with these old sets,especially consoles, but this topped them all.
I knew something was wrong with the way the the original cloth wires to the speaker was wired, so after taking the radio out of the case and cleaning it, I then noticed it had the output transformer under the chassis. Knew someone had botched this together because the Zenith speaker also had an output transformer. I did not have a very readable schematic after paying $8.00 for on from AES. Anyway, I now have a more readable schematic and it was because of that I found the field coil on the new schematic and it's readable resistance value so that I can rewind a new one.
I have a few more caps to replace, then repair and refinish the case, and this will be a nice console. I would like to get an original speaker though. The band slide switches are a mess-caked with dirt and gunk, but I am cleaning those with electronic contact cleaner from AES. Could not get reception on any band until I used the spray while pushing the buttons. Reminds me of the band tower on Zenith TO's.
As to winding new field coils on these old sets, I have had great success with replacing the speakers with PM type and hanging the new field coils inside a small tin can and hiding it in the case somewhere inconspicuous. I had to do this on a couple of Crosleys in my collection. Has anyone else on the Phorum done anything similar?
