I just finished building this one-channel amp whose preamp is based on a Marshall 2550 (no clean setting, however). Power amp is pretty simple: 10-ish Watts, single-ended, cathode-biased, any octal tube, no NFB.
How's the hum at idle? That's the only thing that keeps me from enjoying SE amps at home.
Randy Fay makes the Phaez Jubenile, so he probably came up with that great name. For some reason he doesn't mind me making my custom versions of his amps every once in a while.
There's none of the typical SE hum in this amp because I put an additional stage of filtering before Va.
I kinda think that section of sloclone is silly. lots of amps without diode clipping get stuck in that section (e.g., Friedman PT20); and I bet the Jube would bet put in the 'other noteworthy amps' section because its not made by Friedman or Fortin.

You would think the last amp to need diode clipping would be a small SE with no NFB. All the ingredients are present for making an abundant ruckus.
Very true. The whole dual-clipper circuit between stages 2 and 3 can be replaced by a simple voltage divider, with or without treble peaked. That's how I originally tested this amp actually - and it sounded excellent...
