Built the Tuner and it seems to work well. A couple of questions:

Dan,
1 - My 4SQRP Tuner has a DPDT toggle switch. I suspect your switch
was supplied due to a parts supply issue with the original switch.
2 - Doesn’t sound good. Make sure the polyvaricon mounting screws
aren’t too long, then they might be pressing on the end of the cap plates.
Sounds like a recipe for failure!

I will second Dan. I had one of my caps go bad and you could see the fins buckling up. I suspect yours may either buckle in the future or may be starting to know. The 4SQRP guys are real good about replacing any parts that are not working/bad.
Good luck.

Hello Dan You may have received a switch that’s Not the correct one. We should probably send you another ploy Varicon. That one sounds questionable. Email me direct with your shipping info please. Thanks Johnny ACØBQ
