I wonder how far we are from CNC planes.
I wonder how far we are from CNC planes.
I'm left wondering how my tongue-in-cheek mention of Veritas due to their sometimes successful, sometimes not, innovations in centuries old tool technology has caused axes to be sharpened and torches lit all over town.
As a card-carrying old, fat, white-man I take a back seat to none in my reverence for the past. All my basic circuit designs ceased to evolve past 1930 or so.

I do bring every up to date useful technology to bear in the execution of circuits, though. There are those in my hobby who are aghast at my useage of solid state components like current inrush limiters and voltage regulators but when I feel they improve fidelity or reliability, I don't hesitate.

I just read about a company that makes Holdfasts from wire. Heavens!
0.75" spring wire would likely make a decent hold fast.I just read about a company that makes Holdfasts from wire. Heavens!

Single ended KT88 running as pentodes, or strapped?
You must drive some efficient transducer.
Farthest I waded into the Thermionic pond was Push-Pull Type 50 - glorious mid-range, no heft in the Bass.
You know your stuff.
That's one of a pair of push-pull Mono Blocks, 60 Watts per. Speakers are indeed high efficiency, 15" JBL 2226's with B&C DE-250 Horns. 97dB. The re-issue Gold Lion KT-88 is magical. The low end, being high efficiency, rolls off about 50 Hz but strong and real.
I was strictly a single ended, directly heated triode guy for many years with these speakers. Then this design, an update of the venerable Mullard 5-20 circuit came along. I built it and fell in love. Mahler Second is like sitting in the trombone section again and Who's Next at 90 dB+ is being there.
Missed the itty bitty interstage in the photo.
Is the M 5-20 a Williamson derivative?
While it is true that I have not been here that long, Bill, and don't know you well, I have followed your posts. As well, having shaved my head a couple times a week for the past 25 yrs I am familiar with assorted musings while under the knives, but here, Bill, you are starting to scare me!
