environmental impact of tube production notwithstanding, he'd be okay with them as they are not made to imitate the mind of a human Probably true, but sort of beside my point. Which was that, based on your amp-naming conventions, I'd suspect you for a fanboy . . .

I couldn't slog through Dune when I was an adolescent who was interested in Sci-Fi. I sort of became uninterested in the genre after a while. Now the little reading for pleasure that I get to do tends to run to murder mysteries and spy thrillers.

i don't think i would've had the maturity to make it through, let alone grasp it. in my late 20s it opened my eyes to spirituality, the horrible side of hero-worship/demagoguery/etc. definitely something i needed lived experience to appreciate

output jacks wired, primaries tack soldered to power tube plates (will shorten and solder permanently after i do some testing to confirm that my negative feedback switch doesn't turn on positive feedback and cause oscillation) Does your negative feedback switch turn on positive feedback and cause oscillation? —- off topic 🥀 Maybe you should actively prevent your feedback switch from thinking positively. Then it might lean 100% negative and it could 😢 sadly meet your goal?

i finally got this working right this week. bass knob is a three position rotary switch on the preamp stage cathode: 330nf that's attached to the cathode resistor (so position 1 is nothing), 1uf cap in parallel, and 22uf cap in parallel. there's just enough difference between positions 2 and 3 to notice (which is good. i hate knobs and switches with little effect). for those following along at home that don't already know: increasing the cathode bypass cap increases the gain at lower frequencies.
just like with some of my other recent builds, between control settings and high and low inputs there are a number of different sounds available, anywhere from clean chimey to chunky and overdriven. have to finish getting it in a headshell and while i didn't intend to build a cabinet to go with it i pulled an eminence red white and blues out of a passive floor monitor i was given so a partially open backed 1x12 should suit this nicely
didn't snap any final gutshots yet. i'll get to it eventually

so I've had the four pieces of 1x10 pine cut for a 2x10 cabinet just sitting on my porch for about a year and a half or so. finally put it together and i dig how it looks with the shell for the head. only issue is i much prefer how the eminence red white and blues 12" speaker sounds with the head over the pair of alnico 10" speakers originally intended for the cabinet. so this is taller, skinnier, and not as deep as the 22x18x12 open back cabinet i intended but a 12 would fit.... I'm guessing I'll just need to add more bracing for the baffle?
