Filaments going to 9.7v after loss of HV on all three instances today. This same cavity has been recovered several times due to KMAI and filaments since last year 06/25. Looks like KMAI is holding but when HV is dropped and recovered quickly, this tube is suppose is going into Expert correctly during HV restart so I don't know why HV is dropping . Is this the only cavity that had faults when zone dropped out of HV ? Tube seems to be running ok since recovery earlier so we'll keep an eye on it !

Got the same filaments volts high fault on cavity 8. We may want to drop this one at an opportune time.
