What would be the way to go if I wanted to get a really nice old school tube sound(fairly clean,not looking for too much grind) and keep it ultra light,or as light as I can,I should rephrase.. I've owned an SVT classic,and let me say..never again. I cannot move it to gigs,period. Even an SVT II is pretty heavy for me.. I was considering an Aguilar tube preamp,plus a very light power amp, but from my understanding,just a tube preamp+ a solid state power amp isn't true "tube tone",not like an all tube head.. so it made me wonder..how light do they go?
