Description

General Electric 5U4GB Vintage 1960s Rectifier Tube NOS in Box Tested / Guaranteed

  This Tube and all others I sell, have been tested on a B&K Dyna-Quik Model 700 Dynamic Mutual Conductance Tube Tester and tests at or close to a NOS full Emission /Tube.

 
These are pristine New Old Stock General Electric 5U4GB full-wave rectifier tubes manufactured in 1960s. They come in their original GE boxes and are excellent, authentic replacements for the low-voltage B+ section in the Collins 516F-2 power supply (commonly paired with a 5R4 for HV).Why these?
  • USA-made GE quality known for durability and performance in Collins S-Line/KWM gear.
  • Late-production NOS – untested but guaranteed new/old stock with crisp markings.
  • Preferred by purists over modern reproductions or solid-state conversions for original sound, sag, and aesthetics.
Perfect for restoring or maintaining your Collins 516F-2, vintage amplifiers, or other tube equipment. Photos show date codes and box condition.
