[Amps] Chinese Made Bakelite or mystery material 3-500Z sockets

[Steve Katz]

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...?

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?
