Not a headamp, but what with shelving DIY & all
Finished shoe-horning a rebuilt maggie console amp w/upgd OPTs and dual opamp tone stage into a salvaged Tivo S2 case tonight. Like how it turned out but took wwwaaayyy longer than I expected (what's new

sure learned a lot!) Did take a break to make a portable Tilt EQ and one or two other little projects....
That's a little rebuilt/recased SI t-amp sitting on top of it... Progress is interesting here as both amps crank out within several watts of each other, yet somewhat of size, weight, and power requirements differences
Here's some other shots... The bottom one showing the tight fit in the the S2 case, the orig OPTs, the preamp/tone stage, etc.
BTW, my liking of SOHAs is sorta what spawned this adventure & with a little attention, these old maggies aren't a bad way to try out tubeness.
