Hi all,
After having frequented the towertalk list, i am
new to the amps reflector. Well, wanted that
extra power after the tower has been installed.
Now i do have some stupid questions on Amps.
I am not quite an experienced homebrewer. Especially,
after that RF burn with a 100W rig when playing with
apartment antennas, i am a bit shy. But willing to
safely experiment .{ not yet on homebrewing a QRO amp :) }
I am contemplating on an AL-811/AL-811H.
1) Is the AL-811H the same copy of AL-811, but
has an extra matched tube.??
2) Can i buy an AL-811 and then later, when i
retube it, drop in a matched quad of 572B's to
make it a AL-811H. I assume the 811 will have an
unused tube socket.
3) I have been thru the eham.net reviews on the AL-811's.
A lot of folks have given a big thumbs up for the Amp.
What are the things i should keep in mind when looking out
or testing an amp, if i buy used?? Would you recommend this
for my first amp.
My setup has a TA-33 with the 2KW traps, a TS-440 exciter
and a MFJ-969( 300W tuner).
Sorry about my stupid questions and i do appreciate your
patience and help.
