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).

CV4034 Flying Lead is a Premium Grade, High Reliability Long Life version of CV4003/ECC82/12AU7 valves (Click Here). STC Rochester Plant Date Codes are faint and painted on instead of etching in some of the earlier Brimar flying lead type, and may not be visible on all tubes. Royal Naval Store Depot Copenacre Wilts Stock (see Larger Photo also click on link).

 

Various dated acceptance stamps on the boxes are NOT the date codes and may be of later date. Made in England. Labels are a bit fragile on these tubes since the tubes can rub against the cardboard cone inside the box.
