Read about the CV122 here: http://www.tubecollector.org/cv122.htm
My on going radio project is the recreation of the 1924 Marconi RB12/V4/VB4 smokers cabinet radio.
What's holding up the project is the design of tuning system, the receiver uses spade tuning instead of the usual capacitor and coil arrangement.
To make things even more difficult the receiver covers 300 to 3000 meters in four ranges. I ain't going to easy.
The attachment shows the interior of a Marconi VB4 receiver.
