Like New - $1600 shipped. I prefer US Postal Money Order.
Info:The Groove Tubes award winning all tube Vipre is a variable impedance microphone preamplifier with selectable rise-time and VU meter ranges. It features extremely high bandwidth, low inter-stage feedback, very high gain, enormous dynamic range and graceful overload characteristics.
It has five unique and meaningful features that no other preamp offers. Eight-tubes, fully-differential (balanced) signal path with 75dB total gain via precision 1dB and 5dB stepped attenuators, four variable transformer impendances PLUS two balanced-bridged inputs, five variable rise-time settings, precise VU meter with five viewing options, separate +4dB and -10dB transformer outputs, microphone and +4dB line level balanced inputs. Separate instrument input with two options for input sensitivity.
• All-tube audio path – NO semiconductors, transistors, ICs or electrolytic caps anywhere in the signal path.
• Eight Groove Tube compliment:
4 x 6922 (6DJ8) – preamp and rise-time circuitry
1 x 12AT7 – output driver and rise-time circuitr y
1 x GT6205 – instrument input preamplification
2 x 6AQ5 – Class A push/pull output
• Switch-selectable fully-floating differential input and fully-floating differential output.
• Switch-selectable variable-impedance input, stepped between 300-, 600-, 1200- and 2400-ohm taps off high-performance, custom-wound input transformers.
• Switch-selectable rise-times.
• Precise and repeatable gain settings, in 5dB and 1dB increments from 15dB to 75dB.
• Precision audio metering facilities with expanded and peak views on a true VU meter.
• Robust one watt (+30dBm) output.
• Massive energy storage (>60 joules) in the hightension power supply.
• DC-to-daylight bandwidth (4Hz >100kHz).
• Hand-wired point-to-point connections using highest possible quality components and wires.
• Custom-built ceramic deck attenuators.
• Superior and stable audio performance under the widest range of preamplifier applications.
• Classic design – inside and out.
