YAMAHA B-2 V-fet amplifier demo (fully restored)

Fully restored Yamaha B-2 v-fet amplifier demo. This unit was recently sold on US Audiomart.
The unit is about 8/10 cosmetic condition but it works at better than 100% comparing to its original new condition, considering the power supply and selector upgrades which address some of the very few shortcomings of the original B-2 (see my other videos for details).
The sound signature of this unit is superb. Very airy, three-dimensional and engaging to the point where it is addictive.
There are some kinks with my phone recording. Please ignore.
