Notes

(Note the Set uses all "PM" valves, but the types listed are mentioned in text not on schematic, contemporary examples would have been built with a range of similar 2V triodes as the parts sold separately)

Kit with Cabinet option. Advertised Glasgow Herald Dec. 1928 as Blue print supplied with "Radio for the Million" Vol2 No.4 Sept. 1928

In this period and "Radio for the Million" MW is referred to as "Short Waves" and SW as "Ultra Short Waves".

This set uses a Frame Aerial with optional external Aerial and Earth.

Speaker is a high impedance reed / moving iron paper cone type direct to final Anode and HT.

A Tapped HT battery with GB or a separate GB is used with a 2V lead Acid cell for LT (about 500mA to 700mA depending on exact valves the kit builder purchases.)

Two Mullard "Permacore" audio transformers used.
