PAIR of ALTEC LANSING 846A VALENCIA SPEAKERS and an extraordinarily sounding McIntosh stereo system. The system is from an estate of a friend who purchased the equipment, as best as I can determine, new in the early1970s. He was a non-smoker and took good care of his equipment. The ALTEC LANSING 846As have all green tweeters and 15" woofers. They are serial number 5870 / 391822 and 5877 / 391823. The one speaker (5877) that was opened for the photograph had the 846A tweeter marked 806A 16 ohm 6508. It looks like I was the first person to ever open up the back. The walnut cabinets are still quite nice. There are some veneer chips, mars and abrasions on both speakers. One of the speakers has a piece broken from the right rear, top corner and there are several gouges in the wood. For their age the wood is nice. The grills look good. The McIntosh Stereo equipment consists of the MPI-4 Performance indicator, MC 2105 105 watt the Power Amplifier, MR77 Stereo Tuner, and C28 Preamplifier. All of the pieces were fully functional when the system was hooked up and tested. The McIntosh components have the very nice walnut veneer wood cases and are all in very good condition. Each of the McIntosh components has the original owners and service manuals. The system as shown was hooked up to the ALTEC LANSING speakers and the sound quality was simply astounding.
