NO RESERVE Superb pre-amp really works with just about anything. Two inputs and two outputs, remembers settings for each input (excepting the manual dial) so you dont have to keep track when you change the input. Have used this on a vinyl turntable (to feed a low power tube amp) as well as from a Samsung tv, Sony MD disc player - handles all devices very well. Comes in original box (nothing fancy), no manual or remote

I have used this tube pre amp for about 10 months. It is in good working order, just some dust on it. It sounded great and was a great match to my Metallica turntable.

I bought it new this year and replaced the stock tubes with Genalex 12AX7 Gold Lions (that is what is currently in there). The original stock tubes have never been used! Works great and sounds great! P.s. I’m also listing an upgraded power supply built specifically for the TUBEBOX S2. If interested, please check it out.

Less than 50 hours on the tubes. No original box.
