AX84 Hi-Octane tube amp head:
Handwired by Chris Hurley, the founder of the AX84 project and he's no longer selling them. This is all Point-To-Point Wired.
Controls are Volume-Treble-Mid-Bass-Gain 1-Gain 2.
It has 2 Ei 12AX7 tubes in the preamp and the option of either 1 EL84 output tube (7 watts) or 1 6N1P output tube (1 watt). Tonewise, I'd put this amp as somewhere between a Vox and Marshall with the EL84. Very bright and chimey when clean, all the way up to pretty crunchy and aggressive when distorted. With the 6N1P tube, it becomes very warm and thick (very brown) sounding.
You can truly get this amp down to whisper quiet, even with a 2x12 cab and can crank it all the way up to deafening volume levels. It has outputs for 4, 8, and 16-ohm speakers.
It comes in a pine head cabinet that I built for it. I'll include a stack of 6N1P tubes, enough to last you a lifetime.
$500
