My preamp was purchased new from an authorized BAT dealer. It has been used in a smoke, pet, and child free listening room since then. The unit and it's remote are both cosmetically like they were when I opened the box. The 8 tubes have never been replaced, as they are still very quiet. I checked the unit out before turning it off and removing it from my rack in early June of this year. There appears to be no issues at all. The rating of 8 is for age only. I will not sell outside of the USA & Canada. Please call my cell number with your questions. I am in the eastern time zone and my number is 937-901-2772. I always prefer to have the opportunity to talk with the people I'm doing business with on AudioGon. It is my belief that a few minutes on the phone makes for less chance of any misunderstanding, and is better for both parties involved. My reputation on AudioGon is excellent, as it was during the decade that I operated my audio store. I intend on keeping it that way! I will cover the PayPal fees at my asking price. Thank you for looking, Michael.
