Sansui Q50 Tube Amplifier Monoblock. Replaced all electrolytic and coupling caps with good quality F&T made in Germany. I also have the cage and the two panels that go on the side. You need a step down transformer or a variac to use it. I use it with a variac.
Pretty rare unit, I have been looking for another one unsuccessfully for the past couple of years. If you have one that you want to sell me, reach out. Otherwise, here's yours that may pair your single one. Most probably new production tubes (I usually tube roll mine periodically).
