811KP Surge Kit Glitch Resistor
The large resistor in the surge kit is a special 10-ohm 10kV+ surge rated resistor. It replaces
the small ferrite bead wound with wire.
It adds an additional ten-ohms of surge resistance over the ~8 ohms of the RF plate choke
and ~4 ohms of the filter capacitors. This resistor provides almost 50% reduction in worst
case current surge.
The small ferrite core choke must be removed to install the surge resistor, since that
resistor’s inductance replaces the ferrite choke in RF function.
