[TenTec] Need TenTec 238C Ant Tuner - very wierd antenna switch behavior

My 238C antenna switch has seemingly gone bonkers.

I connect one coax(antenna) to any of the four antenna connectors on
the rear of the unit
and when I switch from antenna 1 to 2 to 3 to 4, I get the same output
to the same single antenna when switched to any of the four positions.

Getting to the switch is a bear so I havent tried to see why the
switch is behaving as if all four positions are connected together.

Anyone had this problem before?

 I am in need for some parts for the TenTec 238
 (plain 238, and NOT 238 B) antenna tuner.
 Hopefully some of you might be able to help.

 Here is what I need:
 Top cover (U shaped, covering top and both sides)
 Plexiglass dial cover, goes along the top front,
 with the dial markings on it.
 Plastic end plates for the front corners
 Knobs
 Toroid balun

 Or, does anyone have a parts unit that might have
 these parts on it? All of my internal parts appear
 to be fine (except balun). Maybe your internal
 parts are dead.

 Please let me know what you might have available.

 Thanks.

 73,

 Ken, W8EK
