You are looking at a used Prima Luna Prologue 2 Integrated Tube Amp with MM Phono Input. It is around three years old is in great shape with minor wear. The Tubes are original, I would replace the KT88's first but the others have allot of life in them. All functions work properly and it sounds fantastic. Buyer pays actual shipping costs, it comes with original triple factory box with foam insert to protect unit as shipped. Fed Ex Ground/Insured Signature Required. I have tried to describe this unit best as possible but it is used and not perfect, therefore no returns accepted SOLD as is. Thanks for looking email me with questions if you have any.Specifications: Output: 40 watts x 2
Freq. Response: 20Hz-30kHz +/- .5dB
THD: Less than 1 percent at full power
S/N Ratio: 89 db
Input Sensitivity: 300mV
Power Consumption: 300 watts
Dimensions: 11 " x 7.5 " x 15.5" (WxHxD)
Weight: 37.5 lbs
Inputs: 4 pair RCA
Outputs: 4 and 8 Ohm speaker taps
Tube Compliment: 2 - 12AX7, 2 - 12AU7, 4 - KT88 Like all ProLogue amplifiers, it boasts: Soft-start circuit Extends component and tube life by powering up the amp gently every time you turn it on.
Tube plate fuse Protects the amplifier output stage. Other amps may need a trip to the shop if a tube fails. Not this one. Just plug in a new tube and fuse, and go. Adaptive AutoBias. Exclusive to PrimaLuna, this circuit monitors and adjusts bias automatically. Each power tube is monitored to stay in a peak operating range. Improved performance and better sound, with distortion reduced by 40 to 50 percent over conventional designs. No need for matched tubes. No bias adjustments. Ever. It also allows you to experiment with different power tubes. Plug in virtually any power tube. Adaptive AutoBias will automatically adjust itself! In addition to EL-34s, you can use 6550, KT88, KT90, 6L6GC, KT66, 7581, EL37, and any of their equivalents. Custom designed output transformers Encapsulated low hum, wide bandwidth for great bass and extended highs. Designed by Marcel Croese and one of the most prestigious transformer designers in the USA . Premium parts . Fully vented chassis, chassis-mounted ceramic tube sockets, Alps potentiometer, Nichicon and Realcap capacitors. WBT style speaker terminals. Gold plated input jacks.
Hand made with the finest point to point wiring, with workmanship equal to or better than any product you can buy at any price, period. Chassis made of finely finished heavy gauge steel, and five step automotive quality finish. Each coat hand rubbed and polished. Removable tube cage included no charge.
Toroidal power transformer for low hum, and a front end that is dead quiet.
Conservative design runs tubes easy for long life. The Phono Board:
Surface Mount Technology implementation for the shortest signal path and reduction of parasitic capacitances and inductance. Made in Holland to ISO 9001 standards and boasting selected components for the best sound quality. Miniature film capacitors, minimelf resistors, and a superior op-amp for lowest noise, highest speed, and robust drive. Low impedance electrolytics and a super low noise power supply results in a turntable experience with goose bumps!
