[Amps] issue with AL-1200 output -UPDATE NUMBER 2-

I have three Collins CU-1169 antenna tuners where each vacuum variable has
spark gaps. Of course being Collins, the gaps are adjustable silver plated
spheres with current sample resistors for the electronic hardware to sense
when an arc has occurred. I am parting-out these couplers if anyone has
interest...

Hii Jim

Would this work in an antenna tuner to keep it from arcing and blowing out
the bandswitch?  How do you know when this is adjusted right?   73
