Audio Research SP5 Pre Amp ?

Due to upgrades and running out of room, I am selling my much loved ARC SP5. This preamp has the house Audio Research sound and is warm and fullsome despite being solid state. It features 5 inputs including its very good on-board phono stage which stands comparison to stand alone units costing several hundred pounds. There is also a tape monitor. The unit Pre-dates CD so I have used the AUX input with a pair of -14bd attenuators which I will include along with a power cable (the captive mains cable was adapted to allow pricy after market IEC cables to be used). The unit was built in 1977 and is still going strong, more technical information can be found on ARCDB. I don`t have the original box but will pack extremely well if required
