Qinpu A-6000 MKII - Integrated /Headphone Amplifier

This listing is for a Qinpu A-6000 MKII - Integrated /Headphone Amplifier.  I purchased it from Amazon in 2014 and am the original owner.  Tubes (6N3 x 2) are original, but the amp received light use.  The product is no longer available on Amazon but the listing/reviews can still be found, as well as equivalent tube replacements/upgrades if desired.
Some notes on the amp:  Power is 16.5 watts-per-channel at 8 ohms, which works for driving bookshelf or efficient speakers (for example, I used it to drive Klipsch LaScalas - famously efficient - and the volume knob never got above 10 o'clock).  The unit has nice binding posts (on top) for speakers, and a mini-plug variable line-out/headphone jack (in the back).  Inputs include one L/R RCA input, two mini-plug inputs.  The power cord is not detachable, and the unit does not include wi-fi/streaming/network capabilities.  However, you can hook it up to your phone and listen to streaming services that way.  It's set up for US voltage.
I'm rating it a "7" due to age, but the unit is cosmetically in great shape.  I'm asking $165 US, which includes the unit, owner's manual and original packaging.  My price includes free shipping in the continental USA (contact me for shipping fees anywhere else).  I accept PayPal, and my price includes PayPal fees.
This is a nice, and impressive looking, old-school amp for a small system.
Thanks
