All interesting I/O points are on a 100 mil grid, so the amplifier can be used as a "macro" on predrilled board (like Vero Powerplane (r)) if the shielding is to be done for the whole assembly. All switching is performed with gettered bistable relays. Monostable relays had too much power dissipation, messing up the offset when switched on or off.

To solve this problem, I found a source of bare FR4 glass epoxy board stock: http://accurateplastics.thomasnet.com/viewitems/epoxyglas-g10-fr4--mil-i-24768-27--nema-fr4/epoxyglas-sup-tm-sup-g10-fr4-panel They offer pre-cut standard size smaller panels of different thicknesses but, unfortunately have a minimum order.

I was guessing the oscillator was a few mils and the buffer maybe 8. The 2n3904 simply does not cut it. Need to do some digging in the ole transistors. Regards Paul.

Most of the time I have seen the MS3106 style connectors used for power on mil spec applications. Does this one look like it is right? http://www.mouser.com/ProductDetail/Amphenol-Industrial/MS3106F14S-1S/?qs=sGAEpiMZZMv%2fye0hRulZR2pdaTIihrgU32yg4H0jMKs%3d If so, you should be able to get it on the surplus market fairly cheap.
