【High-Quality Sound Modified Product】ART TUBE MP Black Lion MOD Vacuum Tube Replacement

This is a modified ART Tube MP, a Black Lion Audio Mod, previously purchased on Yahoo Auctions.

Normally, this would cost over 20,000 yen.
It has only been used for a few hours after purchase.

Below is a quote describing the modifications:
———————————————
Most of the modifications were made by changing component values according to the famous Black Lion Audio modification. The diodes in the power supply section, smoothing capacitors, signal path capacitors, operational amplifiers were replaced, and resistors were also replaced with audio-grade metal film resistors. The decoupling capacitors in the signal path are large-capacity film capacitors, high-quality tantalum capacitors, and Nichicon audio-grade capacitors. The operational amplifier in the input stage is the high-speed National Semiconductor LM6172, and the operational amplifier in the output stage is the high-speed Leniar Technology LT1364. Approximately 50 components in total have been replaced.

Furthermore, the vacuum tube has been replaced with a Russian-made Electro-Harmonix tube (electro harmonix 12AX7EH).

One point to note: upon checking for this listing, I found a slight crackle in the input knob. However, this did not cause any particular issues during recording.
Also, the exterior originally had scratches, but I have listed it as having no noticeable scratches or dirt, as I determined they do not affect usability. Please understand this in advance.
