I can buy this stack: It has the 4x10 TE 1048H cab, and a 400W All-valve poweramp. It has a tube-preamp, but you can also switch to the GP12 transistor pre-amp. It will cost me €600 ($650?). It is 15 years old. Gigged regularly, still in good shape. The gain knob needs some contact spray. Some wear on the finish, otherwise good shape. The backlight is broken. I will play it in a metal band. Any thoughts on this?
