I guess you know RF Parts has #275-TAY which is ceramic and a copy of
the E.F. Johnson #275 that so many commercial houses used for many
years...?

Subject: [Amps] Chinese Made Bakelite or mystery material 3-500Z sockets
Folks,
Still scoping current sources for Amp Parts. Found a Chinese maker of
the classic,
bakelite sockets, that are particularly effiicient at getting free flow
air around the tube
pins. I also remember some years ago a story of some kind of 3-500Z
socket of dubious heritage that had a problem when the alloy pin
contacts were weak and caused problems with the high current filament
pins.
Does anyone know if the Chinese made bakelite sockets are of good
quality?
Best Regards,
