Whatever brand you buy, make sure the filament pins are one solid, welded piece and not a wire soldered to a pin. I am told Amperex tubes are welded and there may be others. The soldered pins are notorious for the solder melting. 73, Bill W6WRT _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
