Trying to find another vendor for the caps we have been experiencing an increase in failures with in our 150kw RF ovens. They’re large ceramic doorknob style 200pF 30KV caps. I can send pics and further specs if you know any distributors.

Thanks. -Zac

Send me the details of what you are using. Im thinking maybe you could swap them out for some vacuum caps instead. MUCH more reliable and definitely available in 200pF

Ceramic disc style not unlike this google image pic, ~2.25" face to face, with M8x1.25 threads in each side.
