Not to disagree with Kim in general, because NiMh are well known for their fast self-discharge, but in 2006 LSD (not what you think, Low Self Discharge) NiMh started to appear. You can usually distinguish these types by the fact that...
The swings you are seeing there, ~150V pk-pk, are using 2N3904 transistor model throughout. The simulator doesn't care that 2N3904 blows up, it doesn't tell me that, just carries on regardless.
When I put in TIP50 + 2N2222,...
OK, point taken.
I can't get the Broskie circuit to work, the opamps are stuck on the rails.
wdiabc, I still can't get your circuit to work in the simulator.

Why would that be necessary? As I pointed out, not a consideration which...

This is obviously a consideration...
You know it fits the same box as the O2? A box is shown on page 6. You do need a drill press and needle files to make it fit. There are sources for the box on page 11 and thereabouts.
A lower resistance relay in the coil...
Hi tyre
Had to change it a bit to get it to work...
...doesn't look too bad in simulation...
This is 580V supply, 250V at the anode.
Input is 1V pk-pk, thru a...
OK, mine doesn't take that long to turn on.
Did you see the note I included in the package about the polarity + on C27 is on the wrong pin? This is the first thing to check. Most turn-on problems have been associated with...
