I have a caddy fully of old television tubes that I came into a couple of years ago. While I can not say that I have any interest in old televisions (I do old radios and homebrew hi-fi), I am contemplating some homebrew radio and transmitter projects. I have noticed that TV tubes come in many more different varieties than the usual triode, pentode, and converter types used in radio. I've already breadboarded an AM transmitter using a 6GH8 to screen modulate the signal- and it sounded good.
In my caddy there are some Beam Deflection Tubes, such as 6ME8 and 6JH8. My queries:
1. How do these things work? What are the variables? For example, we all know that a pentode can vary its output current by either G1, or to a lesser extent by G2.
2. Do you think that these tubes could be used create an audio- variable reactance- treat G1, G2 as a normal pentode and use the beams as the "capacitor" output to control the oscillator in a FM transmitter? Just tinkering.
