Which sockets are you using? The large EF Johnson sockets were designed to be mounted on top of a plate. The bottom of the socket is machined and registered for this purpose, but the upper surface is glazed and only roughly dimensioned. When I designed my 211 amps, I decided early on not to use the top surface of the sockets for mounting. I wanted to be sure there was no slop that could cause vibration, or worse, an uneven mounting surface that might cause the ceramic to crack. The only way to accomplish that was to machine a circular sub-plate that the sockets could sit on. I've never seen anyone else do this, including commercial manufacturers, but I think it's the only way to do it right.
