| Description |
This tube was designed by Ediswan in the ONE-DER receiver made by the company. The tube was not used anywhere else and is not listed in any company literature. A brochure for the radio states "It must be understood that this valve is primarily designed as a single valve loud speaker receiver . and it is no sense a wireless receiver". See BVWS articles in Volume 5, No 4, Volume 10, no 4 and Volume 24, No. The tube was used as a Detector triode and AF triode 1
