I have doubts about the AL82 doing 1500 watts 100% duty cycle for very long.

Knowing the p.s. in that amp you'll be right at its limit, right at
the Ip limit of the tubes, right at or a bit above their maximum

It's a "legal limit" amp only because Ameritron heaped up the Ep.

But you can call almost anything "legal limit" with no time factor considered.

Your enemy is time.  do you want to go for 10 minutes or more at 1500
w. on RTTY?   Do you want to be able to forget about the amp and not
have to look at it nervously every 15 seconds to make sure it's okay?

Personally, I like overbuilt stuff.

you can beef up the AL-82 in some ways and settle for 1.2 or 1.3 KW,
homebrew an amp or keep looking with more money.
