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).

This 1960s Halo Getter Mullard E188CC variant is more desirable than the dimple disk getter tubes from the 70s. In our experience, these are probably the best E188CC/CV4108/7308 type tube made by Mullard.

These tubes are one of a kind. No refunds, exchanges or tube rolling at our expense as it says in the Terms and Conditions on the web site.
