The focus control should be 200K rated for 1W.
There's an Allen Bradlay 2W mil spec Type J pot in there. The resistor is not original.
The pot next to it is horizontal centering while the 3-pos switch is width.
I can't make out a value. I think that's a part# stamped on it. Seems to measure about 150K across.
Boy they sure did tinker with this design.
