Getting Error 45F after rotor start up checked connections on KVP/Filiment board and even changed out board still same error. Reading across XR Tube we get .3 oHms Common to Small and Large. I cecked the AC Voltage at XS-1 and XS-2 and we are getting 30 VAC and then it drops out. How can we verify tube is good.
ERROR 45F
1. Check For Correct Wiring Between J5 Plug On FIL/KVP Board And HV Xformer
2. Check Spark Gaps On H/V Xformer (0.010”)
3. Check That HV Cables Are Not Reversed
4. Check Wiring Of J4 Plug To FIL/KVP Board
5. Check That U18 On FIL/KVP Board Is #1489--NOT #14C89
6. Bad FIL/KVP BOARD (See Additional Notes #3)
7. FIL SHORTED (Check J2-25 On FIL/KVP Board)
8. Insufficient Filament Drive (XS-1 To XS-2 [HV Transformer] = Approximately 17 VAC @
52 KVP With PREP)
9. Loose J3 On Filter Board
