How to minimize current draw when off?
Maybe use oldskool methods, like here?

Grounding modulator sounds plausible, yes. It's not really clearly visible from you picture, but am I seeing some focusing imprefection in your clock? I'm asking because I seem to...

It only says that modulator voltage is -125..0 relative to cathode. From the diagram I guess that they are 6 and 12 are connected inside, while 3 is separate. Meanwhile, a set of...

Here's the datasheed of 6ЛО1И: It's very similar to 3ЛО1И, but it needs slightly larger voltages in general: A1: 45..135V A2: 600..1200V It also...

@peret: in fact I used your schematic as a reference (and your clock for inspiration). Thanks for making it public! If only I could make a circle round... Indeed, even the...

The deflection amp has about 200V. The collector resistor is 2M2, which I'm afraid is too huge for driving a capacitive load. My biggest problem is now to achieve symmetry in the...

Enjoy with me a perfect wireframe of just one of the dark boxes which are about to come: Those darker green patches are not highlights or reflections on the glass, they're some...

Help identifying a resistor, probably
Found here: Quote: Sometimes you might see resistors with all black stripes. Yes, these are zero-ohm resistors and are equivalent to a bit of...

Strange problem with 220V boost converter
It doesn't matter who started this, Giorgos' explanation is still great and highly valued. Thanks, Giorgos! If you would like to continue talking about power conversion, I welcome...

@ossi what a lovely sight! It's really hard to believe that mine is going to be like that one day. Do you have some sort of feedback in your power converter, or do you just let it...

Strange problem with 220V boost converter
In my nixies I used to experimentally find out good pulse width which would be just enough not to saturate the inductor and stick with it. Changing duty cycle is not a very good...
