Hi JP, Mike and Jon, I have several GS10D tubes which just work great in my Anita's. At the moment I've got a MK8, MK9 and MK12 restored to 100% working condition. I've now got four working GS10D tubes out of 16 tubes total. Three of them are in the machines, one is waiting for my other machines to be restored... (three MK8 and another MK12) But to be honest, I'm afraid that within 10 years a few more tubes will be faulty...
That is why I warned JP, just don't trust used or new in box tubes. Most sellers can't test them. Nigel once pointed me to this forum once, and I've asked the same question as JP. I also just wanted to buy a (few) good GS10D. But since I have running machines already, a good tube needs a good home. And that is the MK9 from JP :-) I really hope someone here can help him! That GS10D is key in these machines. It is the 3.4KHz clock divider, it is all about timing in those Anita's. The clock setting mark-skip ratio is very important. If it's not set to the right mark skip ratio your machine will start to make errors. I've tuned down the clock frequency of my MK8 to see how low I can get. I had to do this with an external clock source to remain the mark time and just make the skip time bigger... If I remember correct I could get to about 2,8 KHz. But the machine becomes really unstable then... So I bought an GS10C to try. But this tube won't spin at all. It glows at just one pin. No movement at all... The current trough the tube is too high for that GS10C I think. Funny to note, the current trough the GS10D is also outside the specs of the tube... Jon pointed me to a GS10E which I bought. Still have to test that one... Regards, Roland -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
