I have a near mint QRO HF2000. This amp runs a pair of 3-500z tubes. 85 watts of drive will produce 1500 watts. This is my personal amp that I use daily. It has always been in a smoke free environment. Probably one of the better 3-500 amps, I have had them all down through the years. the noise factor is similar to an AL80b. I added a filter to the right side which uses a washable filter from a vent a hood works great for keeping dust out of the amp. Ham radio Market did a great review of the HF2000 a few years back check it out as well as the reviews on e-ham. If you want a new one it will set you back 3800.00 but you can buy this CHERRY one for a mere 1600.00. I don't want to take a chance and have some shipper destroy it, I would be willing to meet someone in a reasonable distance from Lufkin,Texas and deliver it. I am located 100 miles south on hwy 59 from Houston..I have numerous pictures to a interesting party, let me know and I can e-mail them to you. I can be reached by phone..1-936-699-4637 or e-mail email@example.com Thanks for reading the add best Regards: Ron (WW5US) The hams that have been around for awhile know the record of the QRO HF 2000.
