Zenith 12-S-265 (chassis 1204)
#26

Thanks Russ, due to their smaller size I pretty much use 1 & 2 watt resistors for most applications.

The tuning was very stiff so I needed to access the tuning gears, so I carefully removed the shutter dial assembly. I think the stiffness was a combination of dried out grease and a clock spring that was too tight.

After removing the gears and clock spring I realized I needed to remove the tuning cap. I didn't really want to but it was so filthy there was no way to properly clean it without removing it. After breaking out the Weller soldering gun I finally got it off the chassis and both the tuning cap and the chassis under was indeed filthy. I spent a lot of time spraying the tuning cap with fast drying contact along with an acid brush. I'll let it dry before I take it out to the garage and blow it out with my compressor making sure there are no shorts and lightly lubing it.

With the tuning cap off I spent some more time cleaning the chassis. Cotton balls, Go-Jo, blue paper shop towels and Dollar Store glass cleaner seem to slowly cut through the thick layers of grime.
