Got around to finishing the write-up of the amplifier section of the big two-chassis amp in the wee hours the other day. There are plenty of great two-stage designs out there already but I hadn’t seen anything with a choke loaded input or a regulated power supply. End result of this amplifier sounds great (on headphones or speakers), though it’s tough to say what aspect makes the most contribution.
If you want to try a SET that’s a little more off the beaten path, I recommend it! Amp and power supply can certainly be mixed and matched with other circuits, too.
