Hehe. Funny, but Vinnie has not yet made a tube-based project to my knowledge, so wrong place to joke about it... However, look at the following info about computer power supplies:
"Power requirements for a modern ATX+12V power supply:
+5V(2), +12V (2), -12V, +3.3V
One of the 12V legs is for CD/DVD/Hard drives. You also need an always-on +5V supply for the soft power-on feature of most modern motherboards, as well as the relay control for soft-power on in the power supply itself."
It seems to me Vinnie could easily develop a 12V SLA battery system for the most important 12V rail in computer PS, one that supplies the soundcard, hard drive, etc, leaving all the less important low voltage stuff intact in stock computer PS. With ever-expanding audio PC market, and lack of "audiophile" grade computer PS, heck I'll buy one or two...
