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).
