YC229, and it doesn't require a socket. The grid ring bolts directly to the
chassis.
Hefty grid, instant on, really stable and as nearly bulletproof as a tube
can be.
1500 watt plate dissipation and ratings thru 200MHz.

3CX1000A7 if you can find one and a socket. Its what the 8877 should have
been....bulletproof even at the updated 1500W dissipation.
The pull in my 2M amp will still do 1800W after almost 30 years.
