Great sounding OTL in perfect working order and very good cosmetic condition - rated only 7 because of a hairline scratch on the facie, as shown in the second photo. Else very clean (as also shown in the photos). I am the 2nd owner and this unit has always worked flawlessly. It does require biasing and DC offset adjustments from time to time. Power tubes have no more 100 hours in them and were bought directly from the person in Modena that continues to service Graaf amplifiers. Original box and a copy of the manual included. Price is non-negotiable since it is already quite well priced. Local pick-up only. Paypal adds 3 percent. Thanks for looking.
