Any one ever sell a Dynaco Stereo 80 tube


I have a Stereo 80 tube amp from the early 90's I want to sell but I have no clue what it is worth if anything. I've checked most of the popular sites with none for sale. If anyone has sold one or has seen one for sale could you please give me an idea what it is worth. I want to give someone a good deal but don't want to get a bad one myself. Any help would be appreciated.

Thanks in advance

Best bet is to check eBay for sales of 'Sound Values' tube amps. They were a knock off of the Dynaco, with new parts. I have a set of their mono blocks. My guess is worth no more then $500 if they are fully functional and operational.
