Mike, so you have a 24G26 chassis?
I restored a Zenith Porthole with that chassis.
If you order a Sams, all you get is a schematic for that chassis.
The 24G26 is very similar to the 23G22, 23G25, and 24G24.
You can get the Zenith Service manual at:

The 16EP4 CRT is a hard to find picture tube -- be careful with it.
A lot of us really like Zenith Porthole TVs - tell us about your TV.
