Best value:
Excellent
Audience:
Anyone
I bought it used for home purpose because it was a bargain and because I like tweaking tubes amps.
My cab with a jensen CR10 was already powered by a very powerfull d class amp, I was happy with it behind my modeler, until I used this thing instead.
It gives right away this "cooked amp" feeling, this thing that no modeler can really reproduce (and by the way it gets very hot quickly). No need to push the gain or make it loud, it's deeply there anyway.
I took the time to take it appart and trace the pcb for schematics. It's available on diyaudio. Components and build are fine. On the scope it clips at 7V / 8 ohms (3W rms) and is very linear below that.
As I said previously, as every A class tube amps it gets very hot even idle, and this can lead to issues especially on summer, as tube sockets are soldered directly on the (decent quality & design) PCB.
