I have owned that tuner and now have the 238 (same thing). In my bypass
position neither the cap nor the inductor settings change any swr.
I would say that something is not wired right or has been hit with alot
of rf at a high swr at sometime. Open it up and look for any burned
spots inside. I have found that those "bypass" switches can and do go
bad from time to time especially with high power and high swr together.
Look closely at the wafers on that switch. And yes, possibly wired
wrong from the start. Good luck and Happy Holidays...Steve
