Notes Rider's brings the Stromberg models 250L and 250LB for the same schematic on plan 8-37. Stein (page 203) is in error with 16 tubes. But he shows the same cabinet for 255L with only 4 bands. The model 250L has BC (530-1600 kHz), TROP (1600-4800 kHz), SW1 (4.8-11.0 MHz), SW2 (11.0-22.0 MHz) and SW3 (22.0-60.0 MHz) bands. Tuning eye, AFC circuit, push-pull audio amplifier. For 50 to 60 Hz AC.
