Gil's One Tube Superheterodyne Radio
Here are some pictures of Gil Stacy's One Tube Superhet. It has a regulated B+ power supply that provides 150 volts to the plate of the 6BA7 converter tube. The IF on this 1AD set uses a 265 kHz IF coil, the kind that was used in old car radios. Selectivity is very good. The variable cap is from an old ARC-5 Command Set receiver.
The knob to the lower right is the RF gain/volume control. The rotary switch to the left is the control for the loading coil used for antenna matching. The power supply is fused and uses a four pin Jones plug to connect to power to the radio. An on/off switch and LED power indicator are on the front of the supply.
