I have no idea why Hammond makes their 70's spinett
organs sound like cheesy home organs. No click, dull sound,
cheesy bottom. First we want to recover the key click and
get a better base sound. This first modification is very easy.
Even if you are not technically skilled, you should give it
a try. You need a
working organ
,
some simple tools and minimal experience to do this.
Grab a screwdriver, a cutting pliers and a small soldering iron.
-
Remove back of organ. Remove 3 screws from underside
the upper wood bar.
You should be able to lift the top board at back of the organ a little. To
the front the lid may be fastened in two ways, dependant
of the year of manufacture:
-
with two snap-in-bolts to the front switch panel
which can be unfastened be simply pulling up in one
go,
-
OR it is attached to the side panels with two
wooden dowels which slide into slots in the top
lid. The lid should come up by moving it backwards or
forwards, and the same time forcing it up.
-
Remove metal cover from upper switch assembly. Locate the two
bus
amplifier boards
, they are located behind the drawbar assembly. The
drawbar wires are coded like resistor color rings, BTW: from brown
= drawbar 1 (16' rank) to white = drawbar 9 (1' rank).
