The VTBP-201S has the warmth and dynamic range that only tubes can produce, yet has lower noise specifications than most solid state devices. When the preamplifier is driving a quality power amplifier, it delivers the punch and clarity of the best tube amplifiers plus the almost unlimited power of today's modern power amplifiers.\u003c\/p\u003e  \u003cp\u003eThe VTBP-201S Tube Bass Preamplifier uses a regulated B+ power supply which provides quick transient response with extremely low noise. Regulated DC is supplied to the tube filament which gives the unit extremely low noise. We use only the finest 1\/2 watt, 1% metal film resistors, polypropylene capacitors, high quality, computer grade switches, and a 7025A vacuum tube, factory selected for lowest possible noise and distortion. The VTBP-201S also has a low output impedance which lowers distortion and insures proper power amplifier input matching. Custom toriodal power transformer. New single space rack mount steel chassis.\u003c\/p\u003e  \u003cp\u003eEach preamplifier is carefully hand-wired using only the highest quality parts and tested at Demeter's factory in Templeton, California. You can see as well as hear the quality and attention to detail on both the inside and out.\u003c\/p\u003e  \u003ch3\u003eOperation\/Controls:\u003c\/h3\u003e  \u003cul\u003e \u003cli\u003eInputs: Two inputs are provided: Passive, for normal musical instrument inputs.
