Hi. I have recently gotten my hands on what I think is a very old radio:
I am interested in how this device works. Inside the case is, among other things, a black cylinder containing some circuitry and on its side is a schematic:
I have tried making a hand drawn copy:
I am having a hard time trying to find out what some of these schematic symbols represent and was wondering if anyone in here had knowledge in that area. I am guessing the following is some sort of vacuum tube (a triode?):
I have no idea what the following are:
And finally I am a bit confused about this set of capacitors that are connected by an arrow as if it is some kind of twin variable capacitor:
Sorry if some of the images are a bit unclear.
