Greetings:
First, a bit about myself: I am no keyboardist, only a lowly drummer. But I LOVE music
of all kinds, and have quite the good set of ears.
I have just been given a Hammond J-512, S/N D176757 in fairly good shape.
It has a single-speed Leslie built into it. It also has a "rythym section" that makes the
electronic back-beat for Samba, Ballad, Rock, Parade, etc...
It has no other names on the front or the back, other than "Hammond".
It looks and feels very 70's-ish; especially based on the formal ciruit boards with actual
traces on them (as opposed to solder flow traces (circa 1965), or hand-wired), and
the fact that it actually uses phenolic transistors.
The "Rythym section" is also a dead giveaway for seventies, but was probably
state-of-the-art, wow-gee-whiz stuff at the time.
The lack of any digital IC's (however primitive) suggests pre-1978.
Besides: Analog is good!
I have been unable to find ANY mention of a J-512 on the web. Very unusual, as I can
usually find quite a lot of info on something quite easily.
I was wondering if anyone knew when it was made, what it's current value is, and where
I might could find paperwork on the thing.
The closest I have come is a mention of J-Series Service Manual from
www.hammond-organ.com, which is a guy in the UK.
It does need some tweaking, as some of the keys make sounds out of sequence with
thier neighbors, and I would like a map before I start taking it apart.
In advance: Thanks!
