X-band 12-segment double ring strapped magnetron. 15KV, 10A, 45KW pulse power at 9375MHz; 180W max average disssipation. GEC designed its own derivative of WE 725A. Cathode diameter was larger than the one in the BTH MX57, so that its power could be higher. GEC was asked to make its magnetron fully compatible with the existing CV108 and even with the MX designed by BTH. By the end of 1943 CV208 came fitted with a single cathode/heater glass stem and with a single iron polepiece to be accommodated in the magnet of CV108.

Used as replacement of CV108 in the maintenance of early AI and H2S sets. WE 725A was used for new designs.
