What is it?

15Wx2 Power amplifier with Nutube, a new generation vacuum tube.

This is full parts kit. For completion, moderate soldering experience is required.

Why did you make it?

This is a new version of my previous item. I surely understand the necessity of enclosure for casual use of this type of amplifier. This time I've prepared full enclosure with clear front panel.

What makes it special?

Everything is included in this kit. Clear acrylic front panel and speaker terminal attached back panel.
High quality Aluminum knob (Sato Parts K-59-S-AG) is applied.
As same as previous item, high quality (using Japanese long life and high quality capacitor) 100-240V AC to 12V DC adaptor is included.
The impedance converter is made of MUSES8920 by JRC
Class-D part is by Texas instrument TPA3110. Total sound quality consisting of Nutube, MUSES and TPA3110 is marvelous!
