Why some were red I don't think I ever knew. _______________________________________________________ Is it not so that the red EF50 was the original one, developed by Philips at Eindhoven for television treceivers? Just before Germany occupied The Netherlands on May 10th, 1940, info on the production of the EF50 was passed to on Mullard. The aluminium military equivalent of the EF50 was the VR136, which was used in for instance tuning units of the Gee set; one as RF amplifier, one as a mixer and a VR137 triode as oscillator. 73, Dick, PA0SE
