Steve Weber's COOL 25 Watt Linear Amplifier

I was looking at Steve "Melt Solder" Weber's (fairly) simple SSB rig. I really liked the 25 Watt linear he built for it. Take a look at his technique for mounting the MOSFETS on the big finned heat sink: he just cut holes in the PC board and, through these holes mounted the MOSFETS on the heatsink. Then the rest of the circuit is mounted on the board using our traditional ugly/Manhattan techniques. http://kd1jv.qrpradio.com/ssbrig2/SSB2.HTM
