I am looking at building an all tube television and have some questions about the high voltage supply. In looking at some of the early designs a 1b3 diode was used in conjunction with a beam pentode oscillator. My understanding is that the beam pentode would feed a high frequency into the primary transformer winding and thus creating the high voltage secondary to feed the 1b3. I am thinking of using an oscilloscope tube and will probably need 2-6kv depending on the tube.
My question: could I use a low frequency (60hz) high voltage transformer that are commonly used in ion fan generators, etc? My concern would be that there would be a high ripple voltage due to the low frequency.
