    Hi I have an NCS314 V2.0 that has worked great for about 1-2 years. About 3 days ago the hours digit, NX2 went blank. I assumed tube had died so ordered another. The next day 10’s second NX5 went blank. When I look at them with the scope HV supply is there but all the other pins seem to be at zero. They are driven by different HV chips. Any ideas? Could both HV chips have died withing a couple of days?
    I have another of your nixie clock kits they are so cool!
    Thank You!
