voltage and gap width. an interesting effect that occurs when you connect several of these circuits to the same supply, is that some interaction takes place, as the varying current drawn by the capacitor charge/discharge cycle influences the charge rate of the other capacitors. when you have only or tubes

running, they will sometimes drift into a synchronised pattern. this effect can be augmented by various cross-coupling arrangements between stages, and will be investigated further in future. as the number of tubes increases, the interaction effect tends to avarage out, leading to a more regular beat...
