Simplex Chalmit No.506 400w SON Gear Box, Parry/Parmar Potted Ballast

A recent acquisition, here you see the Parry/Parmar potted ballast within this heavy duty Simplex Chalmit gear box for running 400w SON Lamps on 220/240v supplies. This is a big old heavy lump and must have cost a fortune new. Also it looks a bit like an old high level toilet cistern!
