[LCC] Amplifier

[w5sum at comcast.net]

I have a AL-1500 and I don't think I will EVER own another Amplifier. Its 
tuning is persnicketty when you move frequency by a large margin, but that 
is easy stuff.

I love it

It melts things LOL

The 1200 is a workhorse of an amp with the simplicity needed to work on it
yourself.  The 3CX1200 in that amplifier is expensive but tough as nails.
Treat it right an you'll never have to replace it.  The 91b is an EXCELLENT
amp and has 2 4cx800/gu74b's.  They WERE cheap at one time, but not so much
any longer (but not near as expensive as the 1200 or 8877's or especially
8874's for the Alpha 76/78 owners out there).  But they ARE new old stock
now.   Add that to the uncertainty of Alpha the company.  Is Dishtronix
working on the 91b?  Can you fix the 91b yourself (surface mount IC's,
etc?).  The 1200 can be repaired by almost anyone with a small amount of
soldering knowledge.  I've already changed the relay, bleeders and filter
caps in my 1500, piece of cake.  If I had to work on my Alpha 99, anything
beyond the high voltage or the tube, I'd probably be lost.

Stick with the 1200 unless its low on power and you don't want to buy a
tube.  No need to inherit the uncertainty of the 91b.  I have a spare set of
GU74's, but they're getting old.  I gettered them about a year ago, ran the
heaters without the HV, hopefully to keep them in tact until called to
duty.. but perhaps never?

My 2cents.

Hi guys,

I've currently got an AL-1500 and an AL-1200.  They both serve me well.
However, I've just learned of an Alpha 91b available for sale at what seems
to me a bargain price of $2,400.  If I do this, I'd likely offer the AL-1200
for sale.

What do you guys think?  Stay with what I've got, or go for the Alpha ?
