NOS 1966 Amperex 12ax7s
My NOS input tubes finally arrived, and after only a few hours break-in, I have to say that they sound phenomenal. Huge improvement over the stock Sovteks that the Oto SE shipped with. These are the valves that Peter Qvortrup of AN UK personally recommended to Steve Hoffman for this amplifier... so after waiting six weeks to get a closely-matched pair (same date codes and factory, and testing within 2% of each other) I have to agree with Peter.
