Default Re: KB MR10 sudden fault, help needed

Possibly heat damage as a result of arcing of the HT switch contacts as they have opened and closed over the years. Not sure if it would be possible to bridge the offending contact set with a high voltage suppressor capacitor? If only switching HT this might be OK but a no-no in tuned circuits. Cheers, Jerry
