Tube amp power watts equivalent to Solid State?

Best to avoid clipping totally, however # watts it takes.

As long as its done well.....

I answer to jmcgrogan2's question and to follow up on Drussheaxe's response:
Current US law dictates that:
mercantile products (cotton) are weighed in Avoirdupois ounces
physical bullion (gold) are weighed in Troy ounces.
Avoirdupois ounce = 28.349 grams
Troy ounce = 31.10 grams
Avoirdupois pound = 16 Avoirdupois ounces
Troy pound = 12 Troy ounces
Avoirdupois pound = 453.504 Avoirdupois grams
Troy pound = 373.2 grams
10 pounds of cotton = 4.53584 Kilograms
10 pounds of gold = 3.732 Kilograms

I've owned many tube amps during my 45 years as a musician, sound technician, stunningly handsome bon vivant, and amazingly interesting gasbag. There is not only an appealing tone with tube guitar amps, but a tactile quality that experienced guitar players understand and is sometimes described as "snappiness" or "finger response" or other things I can't remember (I'm old...so SUE ME)...I have also owned a highly regarded (for its time) SS amp, and used it for a while until realizing it sucked. I just bought a cute little Class D Ampeg bass amp that sounds fine, so exceptions are made..."Modeling Amps" also are somewhat popular here and there, but I don't like them. None of this may matter, but I like to take any opportunity to talk about myself hoping that people will like me.

^Don't know enough about you to decide whether or not I like you, but I do like your sense of humor!
I don't typically care if I'm liked. Good thing, or otherwise I'd be terribly disappointed.

Drusstheaxe, please accept my apology for previously misspelling your username.
