2 Ea. US Made, Military E.F.Johnson 4-125,4-250,4-400 tube sockets, refurbished - $26 - (Ark, VA)

2 Ea., E.F Johnson type 275 ceramic sockets. (P/N 122-275-200). Sockets will accommodate the following tube types: 4-125, 4-250, 4-400, 3-500Z, 803, 4D21, 5D22., and others. Removed from military equipment. The 200 designation in the part number indicates heavy duty construction with silver plated contacts/terminals for military applications. E.I.A. base no. A5-19. Desoldered. The govt. used 10 AWG wire on the filament leads by forming the terminal into a circle to accept the heavy gage wire. I left them this way as it is the best way to solder in the heavy gage wire required for the higher power tubes. You can easily straighten them out for other tubes if you like. See photo. Silver plated contacts, clean and bright, no oxidation. Chinese sockets are NOT silver plated and can be difficult to solder. Complete with new stainless steel mounting hardware to accept up to 1/8" thick chassis. Tube base retaining clips and nylon insulating flat washers to protect ceramic base included. Perfect condition. Carefully wrapped, boxed, and in tarnish proof bags All components are US made and meet the highest military standards.
