Jupiter is a subsidiary of KHS /Musix of Taiwan. They market Medici, Advantage, Altus,
among other product lines. The company has factories in Taiwan, Japan, and P.R. China. The
age of Jupiter instruments may be determined by adding one to the first digit of the
serial number. The resulting number then would represent the year after 1984 that the
instrument was manufactured. For example, if the serial number began with a number
"4" you would then add "1" to this number and know that the instrument
was manufactured in 1985. If the first number was a "0", would indicate that the
instrument was manufactured in 1991. The problem with this system is that Jupiter has been
manufacturing instruments for over a decade. As a result, it is not possible to tell if an
instrument having the first number "4" was manufactured in 1985 or 1995. Jupiter
marketed instruments in countries other than the U.S. prior to 1985, so there can be no
real certainty that a Jupiter is not a vintage 1984 or 1985, though it is unlikely.
All Jupiter instruments are manufactured outside the U.S. but those marketed here is this
country are first play-tested before being distributed. A parts catalog is currently
available free of charge from Jupiter. They are eager to sell parts directly to the repair
technician.
If you note any discrepancies, or have additional information concerning
this company, we would appreciate it VERY much if you would pass it on to The Music
Trader. Thank you!
