Hello all, This is the new lamel design with alternating signal-ground. Note that solder connection pads for the cathode foils have been added to minimize the heat load on the glass plates when soldering. This drawing also shows the ID and OD range of our supply of glass plates. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Grant F.
