Mike,

The VFO capacitor is connect to the front knob with a ball reducer and an 
insulating shaft coupler.  The insulating shaft coupler is quite delicate.  
It consists of a 3/4" square of paper, really -- stiff, fiber paper.  

I suspect you tore the 50 year old piece of paper in half.  I did this once 
myself.  I  constructed a replacement out of the back of a thin 3 ring binder 
-- not the hard version binder, one of those thin ones that have just thick 
paper sides.  That was years ago and it's been fine ever since.  

I don't recall the construction of the coupler but it wasn't too tricky.  You 
should be able to figure it out with careful observation.

<< Hello ,


I'm looking for some advise to save me some time. I needed to replace the

25K 4 watt pot on my very early model Johnson Ranger. I guess I was

surprised to learn that I had to completely remove the front panel to get at

the nut holding the pot to the chassis. I thought the nut on the exterior of

the front panel would be all that held the pot in place--wrong again.


Now the panel is off and the VFO shaft seems disconnected from what ever it

is attached to or what ever it drives. I took the side panel off but cant

see anything. Is the shaft for the VFO capacitor just under pressure on some

kind of smooth surface and the friction is what drives it or do I have to

disassemble more to get the shaft reconnected to the variable cap? Thanks

for your help.
