My experience is different.  I have a very early AL 1200 (serial # 089) that I
purchased in 1985.  I have used it in many SSB, CW, and  RTTY contests.
It still puts out as much power as the day I got it.  It still has 
the original tube.
The only problem I ever had was with the fan impeller moving on the shaft
creating a loud racket.  In the early days  I used it with a Drake TR7;
since the early 90's it has been paired with a Yaesu FT1000.  It has
been a great amp.  I hope my ACOM 2000A lasts as long.
