The Rikstone H17 WD  is a one-channel modified version of an old Brittish amp called WEM Dominator III. The original circuit has been modified and a PPIMV master volume has been added. The amp sounds like a Marshall and has a very big headroom. According to the owner it sounds much better than the original WEM. And it is very loud.
