This has been a very long and detailed project.  At first it looked like the TDI Pro board would go into a UK case but it was a tiny bit too small and would have needed Vishay pots.  These are much more durable.  The new Pelican 1170 case is for handguns–quite big but given that many who have tried this project gave up owing to the heat dispersion problem the more air space the better.  This one runs at the same temperature as in the original land case.    The original plastic pot spindles have been replaced with brass–to increase heat dispersion.  The board is shielded on all sides.
