Re: Tek 576 Curve Tracer HV Replacement Transformer
The resistor is there to protect the tripler if the anodetoggle quoted messageShow quoted text
lead is suddenly shorted to ground. It will drag the capacitors
to ground without allowing the current to get high enough to
damage anything... in theory.
However, if the capacitor simply blows up due to the surge
of high voltage/current across the resistor, how does it matter
that the diodes are still good, but the resistor is shattered
into an open circuit condition?
In the 547, that resistor is a 10M 1/4 watt carbon composition
resistor. But the capacitors in the 547 are quite a bit larger
than I believe the 465's tripler's uses.
In the 547's case, I think they were trying to protect the
wayward technician that gets across the live HV. It could
cause a heart arrhythmia in a properly connected person.
