HiFish II completed and tested
« on: August 07, 2016, 08:11:52 pm »
This one is *in the can*!  Updated schematic below.  This amp is a good basis for a bedroom amp, a good compromise between all guitar and all music.  If anyone finds this *interesting*,  Keep the pre-amp, beef up the OT, this version lacks full dynamic range in both Bass and treble, but not enough to re-do. Use a single 6V6, or re-adjust for 6L6.  Once I matted up a 15” altec, the crossover from Voice of the theater, and a JBL pro series 2445H I couldn’t stop grinning!
The *cab* was a quick design, top is harvested walnut, air dried for 30+ years, drawer pulls and some brass rod, my wife *got it*, her comment; “cute, in a Jetsons sorta way”

Special thanks to PRR for helping nail down the design, and HBP for holding my hand through the build – tune phase.
