Emery Sound - Half-Watt Amp


>I have just built a miniature 1/2 W tube power amp that is much better than any of my previous attempts in the micro-power range. I've built a few amps using 12AT7s and such as output tubes, and though they worked well, the inherent sound of triodes is not the classic guitar sound. This most recent amp used a miniature pentode (EF86) fixed-bias, single ended and it puts out a ripping 1/2 W. It is very aggressive and loud sounding at TV-volume levels. It sounds much better than the little triodes. This amp was commissioned by a low-watt fanatic customer of mine and he is mating it with a 1/2 W custom Weber 12" speaker.

>Controls and I/O: Input jack, Speaker Out jack, Standby switch, Power switch.
