300W linear Amplifier for 2200M Band. Original design by WB4JWM https://wb4jwm.com/https://wb4jwm.com/
The fan assembly pictured is for heavy duty operation. In my experience running WSPR or FST4 the heat sink doesn't warm up very much and I don't use a fan. The heat sink is beefy at 8lg x5 5/8 wide with a 3/8 think base.
