 QRO HF-2500  
I am selling a QRO HF2500 Amp from the estate of K8NA. This amp is in excellent condition and I am providing a link to all photo's and a video of the testing by myself and a local buddy with a lab that puts mine to shame. It also comes with a spare tube which was tested in the video. It had two spares, but one was KAPUT. THere are more photos on QRZ. Copy/paste link into browser to see the video.
Price is $2000 shipped to CONUS only and method of payment is cash or Paypal (Not Friends and Family). We prefer pickup as the unit is very heavy. Pickup price is lower obviously. Oh, I forgot to mention it comes with a manual and the original box and packing. Will deliver up to 150 miles from my QTH if needed.
I can be reached at Two For Ate Nine Zero Nine Eight Four Nine Six either text or phone.
Due to parts swappers, etc there is no returns. The video speaks for itself. Link below
