    I’m checking out my 1989 Dual Showman right now to update these specs. It’s the model with no reverb.

    The dimensions of the head are W 27.5 in x H 9.5 in x D 11 in. Just measured mine and I’m one hundred percent on that one. The tube complement consists of three 12AX7A (7025) tubes in the front row, followed by one 12AX7A, one 12AT7, and four 6L6GC’s in the back row. I have all original tubes except for the power amp tubes, a matched set of Mesa Boogie 5881-6L6′s. The corners and handle’s metal parts appear to be black powder coated aluminum. Also, the front mid knob is a pull-out mid cut switch (like a scoop). That function with the treble boost and some chorus/delay give one of my favorite clean settings ever :3

    The Front is as follows: Volume, Treble (pull for boost), Mid (pull for cut), Bass, Channel one/Footswitch inputs x2, Channel two/Parallel channel mode inputs x2, Gain, Treble (pull boost), Mid (pull boost), Bass (pull boost), Presence (pull notch), Volume (pull channel select), Damping Hi/Med/Lo, Output Lo/Hi, Standby, Power, [small red] Pilot Lamp.

    On the back: Fuse (4A-125V Slo Blo), Preamp Out, Power Amp In, Power Amp Thru, Loop Level (-16dBv, -7dBv, +4dBv), Output Bias Adjust, Output Balance Adjust, Footswitch jack, Balanced Line Out, Ext Series out, Main Speaker out, Ext Parallel out, Impedance Selector (4/8/16 ohms).

    I noticed a few discrepancies there, so it’s probably worth looking into.
