Hi,
Need an analogue linear amplifier circuit for 10 MHz. Capable of delivering atleast 10 watts into 50 Ω. The one I designed is delivering only 3 Watts into 50 Ω. Can any one help me. Cost will not effect my project.

I built this circuit long time ago as a driver for an HF 100W Power Amplifier, and works fine.
2SC2078 is a 4W transistor used in CB radios, and for 10W output power you have to replace it with 2SC2509, (10W each). **broken link removed**
This is also a cheap transistor (if you find it).
Beware that you lose approximately 3dB (half of the power in watts) on the output transformer.
