REK-O-KUT TROUBADOUR MOTOR CONVERSION KIT
(Applies to vintage Rek-O-Kut turntables. You will need to modify it to fit other turntables)
This kit consists of the follow:
1) New Premotec Motor
2) Adapter Plate for most vintage and some non Rek-O-Kut turntables
3) Screws to mount new motor to mounting plate
4) Vibration dampening grommets for mounting plate isolation
3) Speedbox and universal, in-line power adapter, but not speedbox mounting screws (see item #3)
4) Screws for mounting plate to deck
1. PREPARE TURNTABLE FOR MODIFICATION
Remove old motor and all mounting hardware. If there are some wire/cable clamps present, you may want to retain them to
dress the wiring of the new unit.
2. ATTACH NEW MOTOR TO ADAPTER PLATE
a) Observe proper mounting side. Use 3 supplied small M2 Metric screws to
mount motor to adapter plate.
b) Insert 3 vibration dampening grommets into plate’s holes that line up with
corresponding holes of the deck.
c) Mount the adapter plate to the turntable deck with the 3 supplied 8-32
screws. Snug them till they contact the vibration grommets, then add an
additional 1/4 turn. Then use 8-32 nuts on the screw ends on the bottom to
lock this position. Tighten only enough to prevent the screws from turning.
d) There may be decks whose mounting holes do not align with our adapter plate. If so you must either drill holes into the
adapter plate or onto the deck and tape them to accept mounting screws. There are too many variations possible, and you will
have to determine how to mount it. Also, if modifying a non-Rek-O-
Kut turnrtable, you want to mount the motor at 8.125 to 8.25" from the
spindle center. You may have to modify/remake the plate. If mounting
directly to your own base, the motor hole diameter should be 1.5 inches.
3. SPEEDBOX MOUNTING
a) Determine where you want to mount the 126 x 47 x 30 mm box. If
not permanently mounting it, skip to item #4. Look underneath and
become familiar with what will be underneath the speedbox. Take into
consideration cabling, as explained in step #4.
b) The speed box mounting holes are on its bottom. They are separated by 100 mm (10 cm). Use an awl or similar to mark the
first hole. Then do the same 100 mm to the side to mark the second hole. Use a 1/8" drill to make the two mounting holes.
c) Determine the length of 6-32 screw to use, and obtain them from a hardware store.
Insert them from the bottom and observe how much they protrude.
It is imperative
that they do not protrude longer than 3/16"
, otherwise they my short the circuit
board or even crack it. If necessary, put washers under the heads of the screws to
coax them to protruding 1/8" to 3/16". Use the shortest screw that works.
d) Fasten the box to the deck. Tighten screws only enough to hold the box on
without it wobbling.
4. CABLING
a) Determine how to rout the motor to speedbox cable, and power adapter cord. You
may be able to use existing holes s with many models. The power switch hole is
often a convenient place from which to route cables.
