Help Identify My New Zenith

[TinCanAlley]

I think I'm going to remove the chassis and put it on a bench for cleaning and testing. The manual has all the resistances and other figures. I'll also make sure the safety caps are done and do them if not. This will then allow me to clean the inside of the cabinet as well.

Now the set has been unplugged for over 24 hrs, but I don't know if that's enough time for an residual voltage to dissipate. I think the procedure is to take a long screwdriver, wrap a wire around the shaft and wrap the other end of the wire to the metal ground of the chassis and then slide the tip of the screwdriver under the cup and touch the connector, right? Or is the a better way to release any stored voltage?

Thanks
