I haven't been active in the forums in years. I'm hoping to change that soon. I only check my email once a quarter at this point.

When I have time, I've mostly been playing with headphone amps. The best one I have built of my own design so far is from my evil twin, AmpSecond. It is a solid state design, output driven by the collector of the power stage, not an emitter follower.

My tube headphone amp didn't pan out, it did soft and sweet nicely, but when it came time to rock, it just wouldn't roll . . . (So much for puns!)

With respect to tubes, on paper, I've been trying to reduce the voltage needed by the power supplies in Gary Pimm's VSAC design. The bias gets quite complicated when you give up the DC coupling from the stacked power supplies.

Play safe and play longer! Don't be an "OUCH!" casualty.
Unplug it, discharge it and measure it (twice) before you touch it.

. . .Oh!. . .Remember: Modifying things voids their warranty.
