 F.S. 25 WATT BROADBAND RF AMP  
i am selling a broadband 25 watt linear amplifier that requies only Zero dBm input to achieve full power out 10 to 90 MHz CW carrier.
This 2-stage, class B linear MOSFET amplifier was designed as a highly linear amplifier by an OEM company in medical imaging. It is re-packeged to contain needed power supplies, a fan and input attenuator. All you need is a good signal generator and a 50 ohm load and your ready to go. Great for testing RF filters and power tubes,or maybe for QRP operation.
I am asking $200 plus shipping to lower 48 states or local pick-up and save the shipping cost. Copy of schematic is included.
i accept cash, check or Postal Money Order.
More pictures and information by request via eMail thru this ad on QTH.COM.
Thanks for reading my offer.
