Hmm, I do not like muxed designs, they make me go crazy ;-) I like the
idea that those poor tubes do not have to flash at some hundred Hertz.
Direct drive usually keeps your program code much simpler, and in case
of a software crash you do not have to fear for your tubes' lives.

This is why I switched to multiplexed microcontroller designs.. MUCH
less soldering. :)

I wish it was only once. ;) have to make about 4 more for the

it worked. Nothing like seeing something completed and working!
