Yes, the EIMAC 1000T will fit the socket. Oddly enough it
has a smaller envelope that the 750T and will use the 50 eattt
socket also. I suspect it was made to provide an easy way to upgrade
existing 450TL designs. The 1000T does require additional cooling air thru
metal tubes to the filament and grid seals. It is an odd ball in the
glass triode series.
