Stunningly beautiful Pioneer QC-800A quadraphonic preamplifier! This rare unit has been recapped with Nichicon PW & FG electrolytics, and Wima film calacitors, and has had all noisy 2sc458 transistors replaced by KSC1845s! A SOLID 9.5 out of 10 condition and a large amount of inputs and outputs. Need to drive one amp in stereo? Works great! Need to drive 2 amps in stereo? Even better! Want to do basic SQ and QS decoding? She'll do that too! This handsome unit sounds AWESOME and comes with a 6 month warranty! If you are looking for a great looking and sounding vintage preamp, definitely consider this Pioneer!
