Can anybody help me locate where the vertical height control is on the chassis of a Zenith Roundie?chassis #25MC30. It's not on the back of the chassis, as is the norm. A photofact would probably be good too.

What is the part number? It should start with 63-. I have a number of NOS Zenith pots.

Sorry Steve, I phrased the question wrong. My problem is that I can't find where the control is actually located on the chassis itself. I could probably just find it by following the traces for the vert. circuit.

On most Zenith roundies, that do not have the pencil box that runs the length of the bottom, the height and V lin. controls are inside the front pencil box. Some have their own small hole others are concentric with a normal pencil box knob hidden in a hollow shaft of the concentric user control.

You will need long thin flat head screwdrivers to adjust them from the front.
