Hi Pete:
I've been running 2 x813 80-10 including 17 &12m for years - full output up
to 29Mhz. 3000v on plate, in Class AB1 (750v on screen) of course 0 grid
current, with no problems.
Last year I purchased a NEW Hammond 10v @ 20A fill XMFR, 4 NEW ceramic tube
sockets, ceramic plate caps and a NEW Hammond 17"x15"X4" aluminum chassis
(still in factory plastic) to build the exact amp you are thinking of
building.
However, illness has unfortunately stopped that project and all of the above
is for sale.
If interested, contact me off list at w4dg at arrl.net.
Good Luck with you project! 813's are almost indestructible!
73, Dennis - W4DG
