Hello, Anyone know what the output is on this old solid state vintage amp? Own one? I'm trying to build a 4x10 cabinet to match it and don't know what speakers to look for. The amp has two unmarked 1/4" speaker outs. The original Holmes cabs were 4x10's loaded with "16 ohm, 20 oz. magnet, 1.5" VC". Other than that, the info is VERY scant on both the amp and even more so with the cabinet. Thanks for any suggestions.
