Dynaco Tube Pre-Amp

I have a Dynaco Pas-4 Tube Pre amp and I need some help determing the market value for this unit. I would like to sell it locally but don't know where to set the price. Any insight would be greatly appreciated.
A lot depends on the condition. I would not try to sell locally because you won't top dollars. You must also state the model pas 2,3,3x etc because it does make a difference. Normal price ranges between 50 and 150 depending on cosmetic and working condition. ooda
Sorry, I did not read your ad very well. The pas 4 should get you around 300 dollars. OOFDA
Thanks for your help Oofda.
