F.S. BROADBAND 25W RF AMP: i am selling a broadband 25 watt linear amplifier that requires only a Zero dBm (1 Milliwatt) input to achieve full power out bandwidth from 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 for medical imaging. It is re-packaged in a 19 inch rack mount unit to contain needed power supplies, a fan and input attenuator. All you need is a good signal generator (or tracking 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 or information by request, via eMail thru this ad on QTH.COM.

with overlapping ranges, and is powered by
120 V AC. All five coils are included.

My asking price is $1200 plus shipping, or I can deliver it to you at any local hamfest. This is very heavy, almost 60 pounds, so shipping will be expensive.
