In case anyone is messing with tube type mobile gear, Murphy's has some of these for $12.95. beats scavenging old radios for them.
https://www.murphyjunk.net/product/gm-delco-2n174a-transistorThese are the large 15 Amp units in the round 1.25" diameter case often used for the plate supply inverter and the modulator. An ARRL handbook showed a pair as a modulator driving a 6.3VCT 20A transformer with the secondary as the modulating winding.
It did not say if used or NOS but the one in the pic looks new so call and ask.
