Hi Don,

My first solid state amp was the Ameritron ALS-600.  When the ALS 1300 came 
out, I sold the 600 and bought the ALS1300 amp.  Both amps have been great 
amps for me and I would highly recommend either.

When I first got the ALS-1300, when I began bringing up the output power, 
the amp suddenly quit.  Ameritron paid shipping both ways and said that I 
had received some missmatch transistors which had caused the problem.  They 
replaced all eight transistors and I have not had a problem since.  40 watts 
drive gives me 1000 watts output and the highest output that I've ever 
gotten was 1384 watts when I was testing the amp right after I got it back 
from Ameritron.

Remember that solid state amps must work in to a low swr.  Unless your 
antennas are really flat, I highly recommend a antenna tuner between the amp 
and your antenna.

Wondered does anyone happen to have a good recommendation on a amp for h.f
that's solid state and no tuning involved?

               Thanks.
