I've been slowly coming to the conclusion that what I need is either an old Hiwatt or build a 50w all-valveguitar amp kit and tweak the EQ values for bass. Firstly I need to get my SC 50PA running to see how much volume it gives.[/quote]
I think you're seeking the unattainable. There's a reason why everyone got rid of their Sound City 50s and 100s as soon as they could.
Decent valve amps like old Hiwatts and Burmans are going to no more portable than the AD200B because of the size of the transformers, which is what makes them sound so good in the first place. Catch 22.
