is this a good way to convert dc currents to ac?

Question

i really don't know if this is a good way but i want to know from the people here
but i have my doubts about the triode
(do all triodes have 4 terminals and how will you be able to see which terminal is which)
and just so you know triodes are obsolete but this is the simplest way i could think of and cheapest
here is the design

Answer 1

Triodes (vacuum tube) are the first devices that could be used as an amplifier. I'm presently looking at your drawing (nice drawing, by the way) and I think I get your drift. Couple questions:
I don't see how/why it oscillates?
What controls the frequency? (LR? - LC? - crystal?)
Two power supplies?
What supply dc voltage to what ac voltage?

Look up the tube chart by the tube number and the pins will be clearly marked.

Answer 2

Some triodes could use 5 pins...

Vacuum tubes may have an isolated cathode which is electrically seperated from the heater. In addition it is also possible to have dual plates and/or combined types in a single package

Vacuum tubes have a numbering system

First number = heater voltage
Letters - First 1/2 of alphabet indicate amplifiers second half indicate diodes and power regulators
Last number = number of pins in use

So a vacuum tube with the following:
6X4 is a diode using 4 pins with a 6VAC heater voltage

12AX7 a combined amplifier and diode 12 VAC heater 7pins in use
