Yes tubes are still quite valid in ham amps.

TV sweep tubes powered many of my HF amplifiers over the years!

Remember those sweep tube KW amps? What was it, 6 tubes in parallel?

I think my old Swan 350 (nicknamed Swan 3-drifty for good reason) used
sweep tubes. Kept within specs they lasted a long time but they didn't
seem to take much out of resonance abuse.

And my Heath mono-banders, wasn't that a sweep compactron?

Yes I was a sweep tube fan also...

Believe me, I've tried most of them, [Rice Boxes]

You've tried *most* of hundreds of models and brands? That seems to be
another unsupportable exaggeration.

We also have a lot of QRP operators (mostly
under 1 Watt) that simply won't be heard by those equipped with the Asian
black boxes!

Now you're being funny. Cause you can't be serious, can you...
