HERE IS A MATCHING PAIR OF VINTAGE VIKING OF MINNEAPOLIS MODEL RP 61 VACUUM TUBE RECORD PLAYBACK AMPLIFIERS. THEY BOTH HAVE THEIR OWN POWER SUPPLIES ADDED. EACH ONE USES 3 TWIN TRIODES AND ARE TUBE RECTIFIED. THEY ARE IN EXCELLENT COSMETIC CONDITION. THEY USE GOOD QUALITY COMPONENTS THROUGHOUT, BUT I’M SURE THEY WILL REQUIRE SOME UPDATING TO WORK AS NEW. THEY ARE FROM THE LATE 50’S OR EARLY 60’S. I THINK THESE ARE PRETTY EARLY MODELS AS THERE ARE NO EYE TUBES IN THESE. VERY COOL UNITS. BUYER PAYS SHIPPING.
