Here are some pics I took this evening.
I pulled the back off and poked around a little, the chassis is really clean but this is a high mileage set as there are very few original Zenith tubes in there, the CRT is one of them.
While I said the CRT was toast really it's just weak, it does work OK as-is.
Flyback looks great with a nice solid tire.
I was able to tune a pretty good picture but the sound is bad with a huge hum, bridging the only filter I could reach made no difference.
Note: don't take flash pictures of a Flash-Matic, it freaks them out.
The third pic is a 21FJ she gave me, it was used and as it turns out was a dud, the red gun is dead.
