Kind of mind blogging. I wonder how many pages the wiring schematic book had? And when a tube went bad you'd need a pickup truck to haul them down to the drug store to test them! That room must have got pretty hot when the machine was on. Neighborhood lights dimmed when they flipped the switch, I'll bet.

We’re on the air! “DC KILOVOLTS” is a pretty terrifying measurement, isn’t it?

It’s time for quarterly #transmitter maintenance at one of my sites today. I always enjoy this one because I get to light up this #VacuumTube powered beauty and put it on the air! Ever since I had that Flexstar exciter repaired, it can even do HD Radio on a tube!

He has an electric hearse and he use to have an electric GM van (NiCad batteries), an electric bus (also NiCad batteries) from the 1980s, and a collection of thousands of...wait for it...vacuum tubes! Another friend, Cindy, wrote this article about Bill last year. https://renonr.com/2022/04/05/the-microchips-great-grandfather-a-look-at-william-brinsmeads-collection-of-vacuum-tubes-and-other-vintage-electronics/

Hi, looking forward if anyone has any "unwanted tubes" and/or "some tubes available for some small projects NOT at IMPOSSIBLE prices". I am NOT looking for stuff like KT88/EL34/etc. more like ECC81 some "final pentode" for some small size "little projects". I live in UK I don't know much "where to look for tubes". I mean last time I really bought a tube was around 10 pounds, now I see the same tubes at 100 pounds each that scares me ! 😱 Thanks in advance foe any info.
