Default Re: Wartime civilian receiver what to replace Westector with ??

That's right, I would have thought the Westector was something quite exotic in 1944. Or, perhaps the device was more plentiful than say, an EA50 thermionic diode. To use the EBL31 double-diode-pentode would have limited the choice of maker to only Mullard.
