H&K say on line those are correspond to a real tube amp but if that's true, still, it's DR-level into an 8 ohm speaker so be sure that's sufficient volume and headroom for you before purchasing.Actually the H&K Blues Master is known as a very Twin like amp/preamp/DI and is known to work extremely well for Jerry tones
Additionally, and this may be only me but FWIW, I've never played a H&K amp I really liked. Though if I someday pull together a Rush tribute band, I'll revisit my decision.
50W is usually plenty of power these days if you mic the speaker - Tons of people gig with Princeton 15W amps actually
