Just bought this set and see that it will need the cover for the illuminated vhf channel (clear plastic?), on/off volume knob is loose (at top) and vhf control knob is missing. Anyone have any parts? The set produces snow and both speakers work well. Not used to color tvs, only B/W older models. Need schematic, these parts or any other infor. Much appreciated! Think it's 1965 model?

Heres the schematic: https://drive.google.com/file/d/1Pk1jV5PFBFbrAk8314qrU5-XyIassqMY/view?usp=sharing

these are a snap to recap and make good images, nice set!

Rototwirbulation...sounds like a Shangoism. I want to thank you for the schematic. Very much appreciated!
