Hi all,
I recently came across a guitar amp that used both sides of a 12AU7a as a 1.5 watt power output phase (connected to an audio transformer).
Where B+ is 270v DC.
I was wondering, is this a safe/practical way to design a low wattage amp? Also, would there be a way to parallel this schematic to add a little more clean headroom? I know the 12AU7 is primarily a preamp tube. I have 2 sitting in my drawer right now, and I've got the preamp thrown together on a breadboard upstairs. Any help would be greatly appreciated!
