Thanks: no need to measure it unless you want to: anything ~10W is really so low it doesn't matter I think (and with the nixies off it sounds more like 1.5W from what you say).

I think all battery holders are like this -- certainly all the ones I've used have been. Slghtly related question: do you know what the power consumption is when the nixies are off (and when they're on I suppose, I have the 5-tube one). Based on holding my hand over it it can't be very high. I'm jus...

Thank you. A hint for people as stupid as me: before you reassemble the thing with the batteries in it, check that there are volts across the battery pack, because it's really easy for the batteries not to make contact properly (this isn't a problem with the battery holder it's just something that t...
