In my experience the only area of the DR7 that is prone to shorting is the left rear corner where a set on Moolex pins reside. It's possible to push it down too far. I solved that problem with some flat stick-on rubber feet on the bottom of the board.

Hi Gary
Funnily enough I made a strip out of clear acrylic which I put on the shelf where the? bulb clips on.
Also put one over the lower level cover and cut out holes for the wires etc.
By bad foil do you mean a strip of printed circuit that is ground?
Will check those out too.
Thanks for the tips.
Kind Regards
