Nagaoka MP-500 in box with unopened accessories, Hum
For offer is an unused MP-500 cartridge obtained as a
collection of Audiophile new cartridges. Upon installation on a head shell on
an Audio Research arm. The cartridge exhibited perfect performance beautiful clarity
but I noted a low level 60 hertz hum. I do not know if the hum was the result
of poor tonearm grounding, bad signal isolation or a fault with the cartridge itself.
The hum was not present in an Ortofon plastic body cartridge mounted on a
different head shell.
NOTE: This is a physically/ cosmetically new item with in the manufacturer's packaging purchased as new with a perfect stylus but a low level hum exhibited when tested. Thus the stylus is guaranteed and the cartridge body should be understood to be is sold as-is, but may prove fully functional on another installation.
In any case I wish to be conservative and assure the buyer
obtains an objectively excellent bargain so the entire cartridge in the box is
being offered for less than the price of the stylus along. If it was my installation
you have just obtained an MP-500 for pennies on the dollar and if there is in fact
some issue with the cartridge body you have obtained a new stylus, box and
display capsule for a substantial discount. Thanks you for your interest.
