Subject: [Amps] 8877 Amplifier Photos
I have just posted many more pictures of my homebrew 8877 amplifier on
Photobucket:
http://s900.photobucket.com/albums/ac206/w7ry/8877%20Amplifier/?start=all
The amp is patterned after the K8RA design that has been in the handbook for
a number of years. I used a switched tuned input board by WD7S. I also used
his amplifier control board and his high voltage board as well.
Let me know if you have any comments or questions. 1500 watts + on all
bands with about 30-40 watts of drive with 4000 volts on the plate.
