You might check MaxGain <http://www.mgs4u.com/relay.htm> for vacuum relays. He has a variety of styles, types and ratings with the associated variety of cost. You can tell him I sent ya but it won't get you any price break. ;-) Alan is very honest and provides excelent service. (He doesn't sell anything he hasn't tested.) He also sells power tubes from Eimac for your QRP rigs. KD4GT/EM74
