So my Ashdown ABM head died on me the other day, I opened it up, and a large chunk of the board is burnt. I had something similar happen years ago with my GK, and the repair wasn't cheap. I'm thinking (since I got a nice tax return) of getting a lightweight class-D head. For the power, it seems Class-D heads are a great deal, and it also seems that's where the industry is heading. Genz Benz heads come up pretty cheap used, although they don't seem very serviceable, it is easy to find a good deal. The way I see it, even if I get a few years out of a class-D head, newer and better stuff is coming out every year. I no longer see a point in carrying around a bulky solid state head, and having it serviced every few years. Tube amps, I get it, but the price of a great head is very good, sometimes cheaper than a major service. Should I make the move?
