Presumably, this tube was for use with those other dreaded 150 mA heater tubes (you know, like 50C5 35W4, 12BE6... ) in line operated receivers with series filaments common from the 40's to the 60's. Other than applying 12 volts to the heater, the pinout and operation of the 1629 is identical to the 6E5. David Anthony DataSpan, inc P.S. Was digging in the back of a 1958 Magnavox black and white last Sunday.. aren't valves FUN ?!?!?!?????!
