Hi and welcome to the forum.

Hi Mark and Welcome.
If you want an original they show up on ebay at times.  The good thing is it is a simple design probe.  1 meg ohm resistor and a switch. I have built many of these using large sharpie pens.  Remove the end and pull the ink tube out.  I have also used pvc tubing as well.  Sometimes we have to get very creative.

Use paint to edit.
Print these out and transfer to circuit boards to make your own extender boards for the Yaesu FT-101

The AC were good tractors. Cut my teeth on a B model when I was 7 years old.

Thanks

Working on putting a 3 point hitch on this one now.

Hi Bill and welcome.
I would need to research those capacitors. 700 volt caps are rare to find these days. Have you tried Hayseed hamfest?
They may have them.

When I need caps like that I put them in series and then put a piece of heat shrink around them making it look like one capacitor.
I have not seen a knight transmitter in so long I am not sure of how the inside looks.

Also thanks for watching the videos.

Buddy
