Dave Slagle / Myemia custom Silver Elmaformers

This is a new version of the Dave Slagle / Myemia custom Silver Elmaformers which uses a 47 position switch and seamlessly goes from -51.25dB to +5dB in 1.25dB steps.  It is essentially a linear version of the Chapman remote modules. 

It all starts with the weakest link and that is the pesky circuit board.  This isn't your everyday board but one made with .9999 silver and the traces are cut on a CNC milling machine.

The 4 deck 47 position Elma switch mounts directly to the board and the wiper contacts are the silver of the board.  I have already run some boards through 20,000 switch rotation cycles without any issues so I am confident in the longevity of the units.

The silver boards are very time consuming to produce and will be reserved for the silver wound units.  For the more pedestrian copper wound units I am getting quotes for the hard gold boards per Elma's spec and will have them in the very near future.
