DA-2000 NUMITRON tubes not driven

OK, I updated the board pictures in the manual:

You must install C1-C6, but you do not need C7-C12.

That is an error on the parts list, thank you for noting it. I will correct it.

Could you show a photo of the board right now, perhaps I can spot something.

Whe you turn it on, the LEDs should be white, then one at a time turn green. If you are still in test mode, the LEDs will start to change colour all together, and the digits on the tubes *should* count.

Everything looks fine.

Please let me have a think about it. I don't see any reason why it should not work. I will think about it at lunch now.
