Mark’s converted combo

Here’s an unloved solid-state amp that’s been given a new lease of life. In this case, Mark has used Amp Maker’s 36W transformer set and JJ valves to turn an old ValveState Marshall into a fire-breathing all-valve amp.

Some jobs were clearly easier than others: “The output transformer fitted into the chassis without modification and the power transformer is mounted underneath at 90 degrees, (but) the front panel is a new piece of steel I welded in.”

The other changes are a Jensen 12-inch alnico speaker and ‘Bluesbreaker’ grille cloth, and the anoraks among us will have spotted the H&K RedBox DI box sitting inside the back of the cabinet.
