secondary tuning, wave length slide
switch. Circular scales (0-100)
There is also a rare battery version of
this radio. It uses the valves A442, A415 and B443.
Some sources mention a
E452T instead of a E442. The E452T was introduced in 1931.
The 1500 ohm volume control suggests a E442. The KY108
does have a E452T and a 3000 ohms volume control.
