I am the 2nd owner and replaced all the tubes earlier this year. The old tubes, which will be included in the sale, were working fine. I do not know what year model this is, but it does have the Hazen Grid Mod. I've rated this a 7 as there is a small area of white dis-colorization right above the power switch in back. It is not visible unless you are looking straight down on top of the unit or you are viewing from behind. It is 100% operational and made my Zu Druid Mark IV's really sing. This unit has one set of inputs. The left and right dials are volume controls. The purchase of ATC SCM 50 active monitors drives the sale.

The output tube section was upgraded with the Hazen Grid Mod pushing the performance and fidelity of the EL34 beyond what any of us thought possible. And the amp is now also compatible with KT77, KT88 and 6550 output tubes. Owners manual can be downloaded at the Decware website.
