NOTE: After spending $$$$ on tooling and various prototypes, we have fitted Special Grade Flying Leads tubes with Custom Bakelite Bases developed in-house. It is a multi-step, labor intensive process. Each lead is straightened and cleaned to ensure perfect fusion with the base pins in the soldering bath. Process is painstakingly slow, so we will be adding a few tubes at a time to the inventory.
Tubes are Plug & Play, Ready to Use, fitted with our Custom made Bakelite Bases (INTL Patent Application in Process).
TUBE BASE ON THESE IS SLIMMER, SO THAT IT WOULD WORK WITH SOCKETS WITH COLLARS IN ADDITION TO ALL REGULAR SOCKETS.
