Bill -

How about a pair of 4-400As as I have 10 NOS ones in original boxes. It is
also used in my T-368F and does a nice job there. I also have a bunch of
PL-172s or 8295s and a pair of those would make a real nice amp. I used to
have an HT-33B that used one of those, and stock it easily put out 1.2KW key

I paid just over $500 for a Pride brand (Chinese) 8877 about four years ago
and it now has hundreds of hours of RTTY contesting on it and still has full
output. It did arc once when it was a few weeks old and blew the AC line
fuses. I replaced the fuses, found no other damage, and it has been perfect
ever since. 

I see that Alpha has gone to a single 8877 in their top of the line
9500 amplifier.

IMO, the best tubes, everything considered, for an amateur amplifier are
either a single 8877 or a pair of 3-500Z's.  Opinions will vary of course,
but for cost, availability and effectiveness either of those is hard to
