This large valve is a 1957 MOD CV1504 Half-wave High Voltage Rectifier Valve.  In very good cosmetic condition, with a few surface scuffs and blemishes, it has not been tested and is sold as a collectible for display only.

Approximate Size: Height: 45.0 Width: 14.5 cm

The valve is etched on the side as follows:-

  • The filament is marked VU504 on one side and 9K-145 on the other.

Since it is unlikely that collectors will use them as intended, some people have looked for alternate uses and have even converted them into novelty lamps!

A nice piece of Electrical history to add to your collection!

NB: Although the valve isn't heavy, it will cost quite a lot to ship due to its size! In the UK this means shipping as a medium parcel.
