  • Notes
  • The model Howard 718APC has a record changer and receives BC (540 - 1700 kHz); TROP (1800 - 5000 kHz) and SW (5.5 - 18.0 MHz) bands. BC band has six push-button station selectors. Tuning eye, push-pull audio amplifier. Stein names it for 1942 a nd with FM, maybe it was still sold in 1942, but we believe that the 12 tube chassis was for AM only. For the 12 tube chassis (4 knobs in line) we know at least models 718 (Beitman names 718X and 718APC and for the 14 tube chassis (five knobs, 2+3) the models 718FM, 718FMC and 718XFMA (or 718FMA). After the WW2 there is also a 718-FM-5-6 and a FM-718. See information about the whole family 718.
