For real cheap money...and particullarly a contest enviroment here are my
suggestions:
160M Dentron Clipperton L...a few $$ in mods and you get 1200W easy
80M Same as above...no mods
40M SB-220 or Clipperton L
20M SB-220 or Clipperton L
15M SB-220 wire so as to bypass bandswitch
10M SB-220 same as above
Dont laugh at the Clipperton....it is damn hard to kill one when run
sanely. If u run xcvrs with built in ATU's ur ahead of the game.
Other cheapies: Hunter 2000C, Drake L4B (both 80-10M); Amp Supply
LK-500(160-10M).
I believe that you are wise to concentrate on glass tube amps...572B's
and 3-500Z's are very forgiving in strange and contest condx.
