This Roland VK-7 belongs to my mate, Alex Richards. The transformer is mounted upside-down on the inside of the top chassis. Guess what? It fell off! The machine was plugged in at the time so the accident caused considerable damage.
To avoid this happening again, I mounted this heavy little component to the bottom (steel) chassis and laid new connections to the power supply board.
Twenty years old, has taken quite a few knocks, it plays and sounds great.
