"Typical" means neither "maximum" nor "recommended", except possibly
within the Conyers city limits.

50mA is not even close to the rated 5w max. grid dissipation, Carl. How
about e-mailing me the JPEG image of this Eimac letter?
BTW, I need some kaput 3cx800A7s to autopsy. If anyone has any, I will
pay the cost of mailing as well any semi-reasonable gratuity.
