A rocker switch allows you to connect the amplification to the chassis and AC ground, or to isolate from it. A second switch allows for bridging the amplifier output. The base of the 2X150VT is painted-black aluminum. The interior of the 2X150VT features modular circuit boards, along with the transformer and capacitors, all sturdily fastened. The power supply includes a 0.9kVA toroidal transformer, and two 22,000-microfarad capacitors.
Rectification is provided for the output, driver, and input stages.
This is accomplished by using a larger transformer core, and subsequently greater primary and secondary windings surrounding the core. To dampen any possible vibrations that still might occur, the transformer has been vacuum-impregnated with epoxy. Components that use vacuum tubes are known, of course, for the sonic characteristics of warmth, smoothness, sweetness, or whatever the description tube fans like to attribute to the sound. Amplifiers that used this design were very well-regarded in their day, but also rather expensive. Another notable aspect of the 2X150VT's design is the fact that the driver and output voltage rails are separate, in that they are connected to separate secondaries on the transformer.
