Tasman cabinet All Wave AW 23

The EH Scott Full-Range High-Fidelity Allwave Receiver, known to enthusiasts as the "Allwave 23," is mostly a 21-tube, 2-chassis receiver, typically set up with a 15-inch electrodynamic woofer 12" and two Jensen Q4 electrodynamic tweeters. It receives 4 bands, which are BC band and three SW bands:  540 - 1530 KHz, 1.53 - 4.0 MHz, 4 - 10 MHz, and 9.5 - 22.6 MHz.  The amplifier/power supply chassis uses two rectifier tubes and four output tubes.  The receiver chassis holds the remainings 15 tubes and two voltage regulators.

Rockford-Peerless built most of the cabinets for Scott in the 1930's. There is also a Scott Tasman cabinet for Chassis AW15.

There is a tuning meter, whose pointer is visible as a shadow on the dial from behind when the dial lamps illuminate the dial. The five knobs, from left to right, are Volume, Bass, Tuning, Sensitivity, and Selectivity/Hi-Fidelity.  Below the tuning knob is the Band Switch lever, and below that is a small push-pull switch to enable the Beat Frequency Oscillator.

This receiver uses 21 tubes and two voltage regulators (VRs), which were counted by EH Scott as 23 tubes total.  The VRs are not counted by RadioMuseum as active devices.  The VRs are NE42 neon bulbs used to stabilize the Oscillator circuit on the receiver chassis.
