Thanks to all for the replies. Have to say that I'd never have matched up the arrow on that picture to something on the tube, based on the text; I couldn't see the arrow on the tube until I knew it was there and had a good peer for it, and reading the Cyrillic phonetically, couldn't guess at any meanings. Think I really do need glasses (and didn't occur to me to chuck it under my assembly microscope.) As regards prototyping, I'm one of the cautious types who tends not to build anything - and certainly won't apply power to anything - until I have exhausted the possibilities of the datasheet/manufacturer's helpdesk/friendly online community. I guess it's a combination of OCD and habits gained working with Expensive Silicon ;-) The PCB in question is actually my prototype for this. I tried going back to matrix board, but find it such a complete pain to wire up, I'd rather do the work in Eagle - which also gives me a schematic for reference - and chuck the whole thing onto Kinsten positive photoresist coated PCB stock. [For smaller, non-prototype, stuff which I don't need in a hurry, I get the boards made by OSHPark.] Thanks again to all; will now press on and assemble the PCB for the little boost converter, then start fine-tuning resistor values. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
