I've decided to sell my Comm Concepts Inc. model AN762 HF 
amplifier.  Its rated at 140w and I get between 130 to 150w depending 
on band (160-10m).  Amp was built from CCI kit:
http://www.communication-concepts.com/140-watt/
And built on 1.5x5.5x6 inch heat sink with 5.5x11x3 inch custom 
chassis.  I added 4-inch fan controlled by thermistor and added a RF 
output 10-bar LED meter (forward power only - front panel switch 
removed).  It has a 7-pos rotary switch for selecting LP filters 
which are not installed (I built the CCI's LP filters but could not 
get low SWR thru them).  PowerPole No. 10awg six-foot power cord included.

I tested 2nd harmonic on 40m at -45dB and at 20m at -40dB running 
100w output into 50-dB attn into my HP141T spectrum analyzer with 
added 20-dB attn.  I recommend not running over 120w which is easily 
does with 2.6 to 4.5w drive depending on band (I can supply 
spreadsheet with measurements).

Funds will go toward buying a KXPA100.
