I finished testing and had a nice pile of mis-behaving tubes that would
snatch to the other end on the first glimpse of FSD and jump about during
ascent and descent. I de-soldered one leg of my reservoir cap so they have
a nice 100Hz ripply supply and they all, instantly, work
Also, anyone thinking of audio VU meters, check out the MSGEQ7 chip if you
have not already, i have a dozen or so from this seller

work project (audio - DMX) and they worked wonders, nice stable DC level

Quick question,
Why would you need a soft / slow rise time on the anode cut off to reduce
switching noise when the cathodes are toggled repeatedly by the 74141?
Surely that introduces just the same switching noise that would be produced
with just a high side switching FET or BJT? Or does the
Ahh, of course. The whole topic being on multiplexing should really of been
the clue there. silly me...
