when I was young living oversea's ( growing up with tube radio's & amplifiers Teac decks Mullard, Murphy's Telefunken etc etc ) we owned the largest Philips electronic agency in the country and for High end audio we alway seemed to use porcelain connectors, recently I found some on E-bay from a company in Hungry, brought back old memories, I guess I'll order some with silver wires and porcelain connectors the pins are gold plated
