6146 or 807 would have been a great choice, with their anode connection on the top cap. No chance of flashover on the base like when pumping a pair of 6CA7s at 100 watts with 1600v peak on the anode pin. Also keeps the high level signal away from low level stuff. Maybe 6146 was simply a bit expensive?

I think it's important to differentiate between tube hi fi, and tube guitar and recording equipment.

Guitar, and recording are subjective things. It's not math at that level. Sure, old tube compressors are inferior from an engineering standpoint, but to many those flaws sound good. Saying that's not valid is like saying some colors are better than others for art.

Yes, and taking this a step further, tube guitar and tube recording equipment are generally on different planets (the latter's traditional goal being linearity).

Good points. I would add that the "soft knee" / "vari-mu" characteristics of tube compressors are superior from an engineering standpoint, depending on what one is trying to achieve.

They can do a hell of a lot more than be used for music, and the size of them really brings electricity up to our scale.

Solid state is for achieving a precise end result by a deadline on a weekday.
Vacuum tubes are for relaxing and enjoying yourself on the weekend.
