That makes me feel funny in my pants.

are valve watts special? Coz there was only 10 of them. I could imagine going as low as 30-40 watts but no lower. very minimal though. do love that.

Is there any actual point?

peat, kinda yes, kinda no. There aren't high power valve amps, and they need to be paired with a high-sensitivity speaker and driven quite hard but you can definitely get a whole heap of volume out of one.
Greatest setup I ever heard had a 15W valve amp driving it.

Hmmm, there is every chance this would be less than, say, a grand. Keeeeeeeeeen
