I have a Curtis Mathes Proj. Model 4620PMK, with 2 Zenith modules side by side, no chassis stickers on the modules. Does anyone have a cross reference to the module numbers? Or a manual of this model to share? The red tube is real milky (looking inside), video has a "bad" red glow around anything red on the screen. I think the fluid needs changing bad. I've never changed the fluid in one of these before, trying to find a diagram on removing the red tube. Can onyone help with this? Thanks. David.
