This is a re-listing of an item that has already sold. A refund was issued because the package appeared to be lost in the mail but shortly after the refund was issued the buyer received the package. This listing exists so that the seller can be paid. I am not %100 sure whether the amplifier works. The blue lights on it blinks when powered on and the amp does not produce sound for my speakers. I used this amplifier frequently for about ten years and in that time I never replaced the tube bulbs. So I strongly suspect that they are issue and that beyond that the amplifier works fine. After years of absolutely loving this amp I decided it was finally time to move onto something new when it stopped working. If you would like to purchase the amp and install some new tubes to see if it works here’s an opportunity to acquire a great tube amp for a decent price. Perhaps you are also interested in it for parts. Let me know if you have any questions. Thanks!
