A much revered Quad (Acoustical Manufacturing Co. Ltd. of England) Model 33 preamp. This had been completely rebuilt with the Dada upgrades. New electrolytic caps, new transistors, new volume and balance controls, new spark supression cap, many new carbon film resistors. Included are two DIN to RCA adapter cables and a new AC cable. This has been my personal high end preamp for several years, but I have moved on to other things.
