That’s probably either a step start resistor or a glitch resistor. I would
have to look at the schematic. Depending on which it is will depend on the
nature of the fault. In either case it could be a tube failure a HV short to
ground or a bad step start relay. I’ll check the schematic.

Our Alpha 8100 has incurred a failure. Currently have identified that R9 , a
25 ohm, 25 watt ceramic wire wound resistor has overheated and melted some of
the ceramic coating. Has anyone seen this failure mode and if so, identified
the root cause ?
Thank you,
