All: I have had pfg connection problems for a month or so. They
coinsided with vnmr 6.1A. However, the problem was in the upper stack. We
found a cold solder joint between the wires and the feedthroughs. I also
replaced U2 with rev. Z. Results with Shaka's dpfgsenoe sequence are solid
now. The wires etc. take a beating from the 'loud speaker' effect.
Cheers, Lew
