Good on you!  That's always fun.

Get yourself a couple of retired medical instruments called 
"hemostats" and/or "needle-drivers".  I've got some small, short 
ones, and some really long ones.  I can reach wayyy down into the 
innards of an amp and retrieve such parts.

Such things are good for glass tubes, to help cool the glass-to-metal 
seal.  Compared to the the 3-500z, the 4cx800a's anode connector 
already has a MONSTER finned heat sink, doesn't it?!  All you need is 
an electrical connection, really... and plenty of cooling air through 
the anode cooler.

Have fun with your new amp.  I'm betting you'll like it.
