1. Keep the B+ reasonable. It IS possible to run EL84 PPP ultralinear
at 425V, if you handpick the tubes... using a B+ of 350 or less
will avoid a lot of potential problems.

What's the screen voltage? If you keep the screen voltage at a reasonable
value, the plate voltage can be very high without hurting the tube, actually,
the limitation is usually the socket rather than the tube. The dilectric strength
of a vacuum is pretty good.
Just out of curiousity, what model of amp is that, anyway?
