Small and functional
Worked perfectly for my application. A small bluetooth speaker. Sounds clear and really does the work. Light weight and small. Exactly what I needed.

Good sound quality.
I plugged it on a sure power amp I have. It really makes it sound better. I used 3 Mullard 12AX7 tubes. The only complain is that the transformer runs HOT. Very hot! I'm gonna make some more tests see if it will last.

Nice tube Pre
I tested it for several hours as a pre-amp while working on another project. Sounds really good, no noticeable background noise. Crisp and clear. It does get really hot. Next I'll switch the tubes by GE JAN 5654 and listen again.
