One of the earlier uses of the 1232 tube in the RF stage is found in the 1940 series of Philco radios.- this specific tube is still functioning quite well (and tests above 300 Gm on my Hickok 752A tester) in the Philco 40-180 console I have restored. Please note that an "equivalent" dual-designation tube 1232/7G7 was also produced; shortly before the tube was replaced by the 7G7 designation. Robert Attachments:
