Yeppers! I still stay keyed up courtesy of a footswitch while I replace the 9V on my TUG-8 D104. :biggrin:

My Dad was into ham radio big time, had the highest level FCC license you could get. His final stage was 3K watts (class C amp) and those tubes were huge!. '50 beam on a '75 foot tower, neighbors thought it was a huge TV antenna until he cranked up that bad boy!, even with all sorts of exotic filtering there were still issues, sometimes talking on the phone you would hear it an even on occasion it would make it's way through a speaker coil, even if the stereo was off at the time!.

3kW even PEP needs a decent sized gamma match if your driven elements are fed that way. Coronas and arcing can be mad at those levels.

I know they came as a matched pair, he had "CQ" cards from all over the world and was part of a civilian network ( I forget what it was called). Basically radio was a common hobby of his generation and he had it pretty much maxed out. Sometimes during transmit the light bulbs would noticeably dim and brighten along with the modulation peaks!..

Neat!

There can't be many that know the art tube-rolling.

Makes me sad I sold all of my tubed audio equipment. 🙁

She meant this type of tube:

Thats a tube that I could get into.
