Does anyone have any advice on the "picky power supply" issue? My power supply
seems to be within spec. The plug-ins I'm using work fine on a 7514 and a
7704A. But on the 7904, if I try to use a full complement of four plug-ins
things usually get flaky (readout becomes garbled on some plug-ins, the 7D14
counter stops working, etc.). It works with three plug-ins, but does "tic" a
couple of times at start up.

I've been considering recapping the regulated supplies to see if that helps.
