I have just spent a couple of hours with a colleague going through the issues that I was experiencing with the HV Supply. There was the data corruption and more recently - once I had added the last four out of 10 tubes, the HV would start and then instantly go 'off' only to come back on some 10 seconds (or more) later.
The data corruption issue was exactly as foretold - ground returns. I added a ground return for the data signal from the micros which had an immediate effect, no corruption. I will almost certainly add another for the 170V ground return for completeness. The other issue, after much scratching of heads, was resolved when some rough calculations took place, causing me to check the 12V power adapter that I had been using - 12V 1000ma - Doh! I moved to using a spare output on a much larger 12V supply that I am using to drive multiple clocks and immediate success was obtained there too. So, now I have the proper supply, connected to a proper supply and it's all lovely. Thank you Kevin and everyone else who provided pointers. I have learnt a lot during this process, hopefully I will remember some of it when I get to use the second of the two HV supplies! Top marks, excellent product, excellent support, thanks again.
