Re: Sync Rotary = 120bps? (was:Re: rotery for neons)
to: Reinhard
With a non-synch RSG there is a tendency to run the rate higher, perhaps
only for a short period of time to "see what if", and this treatment usually
quickly blows the NST. With an 1800 rpm 4 electrode snychro RSG then it
fires on each peak and the idea of "pushing it" doesn't present itself.
In accordance with MoreCroft, if the gap fails to fire the tank circuit
usually sees 2X or even 3X the resonant potential when it does fire and this
is a problem.
