A reply to all who gave me the input on their upgrades, excellent information.
I
found
the modification going to the 3CX800A7 tube fairly easy. Did have a problem
coming
up with chimneys for the new tubes.
The amplifier works excellent, and does not require much drive to make 1500 pep
output. The unit is quiet and very stable.
Thanks for all the information. The Alpha is a very fine amplifier, watch the
grid
current,
load a bit heavy and really powerful.
