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. It has a.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 that contains needed power supplies, a fan and input attenuator. All you need is a good signal source (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.

FS: OM Power OM4000A: Selling my OM4000A as solid state amps better suite my operating style.
The OM4000A is just back from OM Power's U.S. service center, and has had two new tubes matched by OM Power installed. It is in excellent condition with now scratches or other issues. Inside, it is bright and shiny, and is a joy to look at.
To give you a sense of the overhead this amp has, into my Alpha 2000 dummy load, I measured the following with an LP-700 wattmeter:
160m 9.1 in/801 out 13 in/1299 out / 17.1 in / 19.5 out / 25.1 in / 3268 out
10m: 12.5 watts in/2012 watts out.
Included with the amp is the OM4000A remote control unit, which allows you to turn it on/off, put it in standby/online, and also displays the power. Additionally, there is an embroidered cover to keep it dust-free. The original box and packing materials are included also.
$6250 - get it before the tariffs kick in. An OM4001A (the successor to the OM4000A) is currently $9,300 at DXE.
