10 watt Power Amp. with IFR510

"Using cheap Power-FET's in the HAM-shack is a wonderful feeling."

Comments: 

• Be careful to make as short as possible Source/GND-connection.
• Same for Resistor R3 and R4 (100 Ohm) to Gate.
• Cut of the DRAIN-pin and use the mounting-set in stead.
• Use Aluminium Oxide Insulation material only between Drain and Heat sink
• Solder small double sided print-points to mount on
• Be sure that your Heat sink is big enough.
• Use a Lab. Power supply with Current-regulation to start it up.
