Morris, maybe try having an idle current in all the lamps - just at the
filament starts glowing point [not visibly glowing].
Re LEDs, I noticed some small LED Xmas lights that had a bezel with an inverted
cone - apex pointing at the LED. They spread light around 'differently'.

That's exactly what I've done. As the bulbs failed I saved them and managed
to remove the innards while saving the base and not cutting my fingers in
the process :-) A 5 mm LED fits in nicely.
John K's suggestion about idling current is a good one, but it will
involve a rebuild of the
Hi,
I think you have a timing issue. Your code turns on the anode and then
changes the cathode.
Try modifying each tubx() routine to turn on the cathode first, then
delay one millisecond, then turn on the anode.

Yes, alter your timing, as David suggested.
But also, those 100K resistors across the bases and emitters, of those A92s
can be made smaller. Say 10K. The junction, will keep the voltage below
0.7V, so most of the current will still flow thru those junctions. Those
resistors' primary purpose is
You see I am a chinese,and I had a lot of NOT FAKE LM9022 made by NS
all brand new in org pack,and as me experiance in driving VFD stuffs
,I only used this chip in one project,and I think this chip is too old
for the current tech,by using only two mosfets and drived via a MCU

John,
That's called a 'bat-wing' named to the shape of the radiation diagram.
You can get LED's with such a housing (Power LEDs in any case).
