-= Next Generation DC Readout Notes =
 * Put the resistors on the PD block, not the nipple.
 * Wider separation for the PDs so the ghost beam can get wedged out.
 * Black glass ring around the PD cans
 * Black glass dumps all over the place for the leak throughs.
 * Don't use any of the Piezo-Jena crap.
 * Don't use copper for the OMC body. All fused-silica, all the time.
