    i have one of these that i purchased from an old friend Jeff Dunn (son of Duck Dunn) it once belonged to his father.wondering about it’s value and where i may pick up some original or as close to original tubes.

    I’m not sure about how to value the amp without having it in our possession, however, you can certainly pick up some new tubes from mojotone.com

    i have one of these here in the uk have had it a few years its moved around with me through the years and yes its loud and also heavy to lump around and it still works did have some tubes replaced but not the originals they were close alternatives i would say the amp is worth as much as it is worth to you i was offered 1000 pounds in 1989 by the engineer who worked on it at the time but this was in the uk where they are rare
