I worked at Speer Carbon Company back then. We made those carbon/graphite plates for the 813's, 811's and several other tubes. We wore white gloves while handling the material. If oil from our hands got on those parts they would not survive when they heated up. 73 George/W2BPI ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected]
