XTONEBOX Silver 6011 - Oak Finish (Extra Tubes)

XTONEBOX Stereo Tube integrated amplifier with built-in Bluetooth and Phone Pre-amp in Oak Wood Finish. Item will come with User Manual, Power Brick, 4 rubber tube gaskets and 4 vacuum tubes. In addition, I will throw in (not literally...LOL) an extra 2 sets of Tubes and gaskets at no cost (4 tubes total). Below are the details on the tubes that will come with the unit:

2x - Tung-Sol (Model - 12AX7) - Made in Russia
2x - Electro Harmonix (Model - 12AX7EH) - Made in Russia
4x - JJ Electronic (Model - ECC83S) - Made in Slovak Republic

Amplifier unit is hand made in Spain. (Not Refurbished and Not B-Stock)

NOTE: Those not familiar with these units, here is a trademark with all XTONEBOX Silver units: When powering off, a "thump" sound emits from the speakers, which is per design and NOT a defect with the unit. It personally doesn’t bother me, but it may bother some.
So, the million $ question, why does the "thump" sound happen? Answer: When switching off the power to the amplifier, the power supply will collapse asymmetrically, which will cause the amplifier’s output to be at an indeterminate state (when it should remain at zero DC). This results in the switch Off thump. BTW - Most amplifiers will contain an output relay to negate this behavior - the relay is energized or de-energized only when the amplifier’s output is stable.

Anyway, I am conservatively rating the item at 8/10, however it is in pristine condition. All attached pictures are of actual item. I do not have the original box, however, unit will be double boxed for shipping. I will only ship within the contiguous U.S. Specs can be found using the URL below: https://www.xtonebox.com/product/silver-6011/
