** ADD 3% FOR PAYPAL The BC3000 design to the next level of musicality and represents the state of the art in single ended Blue Circle preamplifiers. When it comes to making improvements in quality components, there is a law of diminishing returns. What we mean is that moving from one quality level to a higher level becomes more and more difficult as the quality increases. After all, the fundamentals of circuit design have not been completely changed by us or anyone else. In order to produce an electronic component that stands at the pinnacle of sound reproduction, it is the little things, the attention to the most minute detail, that allows one to move from an already high level of excellence to the next. The devil really is in the details. The result is a component that is significantly superior to any other single ended preamplifier we have built to date. Every individual component, every connection, every subsystem and every completed preamplifier is tested, evaluated and tested again. Each unit is lovingly hand-assembled and listened to by a small group of highly trained specialists The Power Supply is the same BCG3.1 MKII high current dual-transformer design used for the BC3 Galatea MKII. Filtering is both massive and very very fast. The rectification circuitry employs HEXFRED diodes. Airborne Wiring is employed throughout. This is a technique where all signal path and power supply wiring is kept suspended. This results in lower signal loss, better transient response and improved linearity. Through a rethinking of tube bias and current source circuitry, we have managed to squeeze more linearity out of the tube response. Single-ended Class A dual triode design with very high gain remains our basic design philosophy. *The BC3000 MKII employs true film and foil capacitors at the output (from a transparency point of view Blue Circle film & foil caps are about as close to a piece of wire as you can get)wheras the BC3 MKII uses metalized polypropylene capacitors. Residual noise reference to full rated output: >-110dB or <65uV non weighted Residual noise reference to full rated output: >-120dB or <22uV within audio band Hum below 400Hz: >-143dB or <1.5uV Tracking error tube stage: < +/-0.1dB Tracking error volume control: <+/-0.038dB Channel separation: >107.5dB Frequency response at 15V output: 10Hz to 40K +0.00db, -0.1dB; -1db at 70kHz; -3db at >100kHz Distortion at 1V output: <0.05 % Voltage gain: 23.5 dB Maximum output: 25 Vrms volume control range: -95dB to 0db in 62 steps standard in Shallco attenuators input impedance: 100Kohms output impedance: 180ohms Technical Information: *5 Line level inputs, 1 loop input (3 line level inputs for balanced version) *Optional USB input available *2 Pre-amp outputs, 1 loop output *Tube complement: 2-6922 *Power requirement: 120Vac 50/60Hz 38Watts - available in 100, 220, 240 Vac *Dimensions: -Main chassis: 17.5" (width) x 3.25" (height) x 14.6" (depth) -BCG3.1: 6" (width) x 5.375" (height) x 14.6" (depth) Weight (without packaging): -BC3000: 37 lbs. -BCG3.1: 16lbs.
