Problem with thermionic tubes are the vulnerability to a kind of cathode poisoning due to lack of current in 'zero time' and the high power consumption. Best should be 'computer grade tubes' like E90CC and E92CC They have specially coated cathodes eric _____

Ah, that's a shame - on the basis that the XD18 is to be had plentifully, and at a sensible price. Wonder if it's possible to replace a thermionic triode with a transistor of some description - rather than going the microcontroller route, which I still think seems to be a bit of an overkill, and not really in keeping with the aesthetic I'm looking for. 20V in, 60V down - just an inverter with a gain of 3, isn't it? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
