Year-End Special Price Luxman LXV-OT6 Vacuum Tube Harmonizer, Fully Functional, Beautiful Condition, with Bonus Item

Thank you for looking.
Christmas or Year-End Special Price Change (Discount)!

This is a listing for the LUXMAN Vacuum Tube Harmonizer (LXV-OT6) released by Ongaku no Tomo Sha.
I carefully assembled and used this simple kit product, but since I purchased two units, the usage frequency was low, so I am listing one unit in excellent condition.
The operation has been confirmed before listing, and it is a beautiful item with no noticeable scratches.

I believe an explanation of how to use it is unnecessary, but it is installed (RCA cable) between a CD player, etc., and an amplifier to convert digital sound into analog vacuum tube sound.

Included with the assembled Vacuum Tube Harmonizer main unit are the power cable and the original box that contained the assembly kit. Additionally, to provide enjoyment for the buyer, I will include three vacuum tubes purchased separately from the ones that came with the assembly kit:
1. GE
2. Mullard
3. Electro-Harmonix
All are 12AU7 (ECC82). Some of these vacuum tubes were purchased used. While I believe they are all in good working order, I cannot guarantee their operation, so please understand this in advance.
