Hank,  W6SX is having trbl with his roller inductor:
"I recently returned to the air after an eight year absence.  The 
roller inductors in my Nye MB-V-A and my Ten Tec 4229 antenna tuners 
have corroded and are intermittent.  I have squirted contact cleaner 
on the coils and rollers and run the rollers back and forth with no 
improvement.  Does anyone have any suggestions?"

Hank,  I've found that simply squirting them doesn't do it. I spray the contact 
cleaner on a cloth and then hold the cloth against the inductor while rotating 
it back and forth. You won't believe the crud that comes off. I also clean the 
shaft that the little roller contact rides on and then apply a VERY SMALL 
amount of commercial no-alox type stuff on the shaft and then run the inductor 
from one end to the other several times to make sure the shaft is covered.

Good luck with your tuner.
