V0 - LEMO 'ntny' connector type not easily available
About the stacked LEMO connectors on the front-panel.
epy.00.250ntny is not easily available on the market. LEMO sells them,
but they are rather expensive.
epy.00.250ntn (without the 'y') is on stock, but is 1mm higher and would not fit a VME panel.
O.B. is checking out with LEMO.
