A 200 Watt tube amp?!
That's impossible. 
Not if you completely enclose the power output tubes AND the drive electronics in a dielectric fluid. So that is exactly what we did. Believe it or not, tube amplifiers are not only back, but state of the art in home audio. The Von Gaylord "UNI" monoblock amp shown above (you need a pair for stereo) is a work of art. From the massive turned aluminum feet, laser etched logo bezel and nameplate, powder coated enclosure, to the grey anodized aluminum capped glass dielectric chamber, this amp ROCKS! If you have to ask how much does it cost, you can't afford it!
