ESOTERIC SOUND REK-O-KUT TROUBADOUR User manual
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.
b) Rout the motor cable from the speedbox to the motor
and solder its end to the motor. The white lead connects
to the “+” sign on the motor tab. Do not linger while
soldering and use only enough heat to melt the solder
and have it adhere the wire to the tab.
c) If available, use existing cable clamps to dress the
leads into a convenient place.
5. CALIBRATION.
The box is factory adjusted to provide almost the correct speed.
a) Set the START/STOP switch to STOP, the SPEED switch to 33, and the CAL/VAR switch to CAL.
b) Plug the power adapter into a convenient power outlet.
c) Switch to START. Using a strobe disc on the platter and viewing with incandescent or florescent light, calibrate each speed
with a small screwdriver.
6. OPERATION
a) Use the START/STOP switch to start platter rotation or top it.
b) Normal position of the CAL/VAR switch it CAL. To vary pitch, set the switch to VAR and rotate the PITCH switch to
obtain the desired speed. A very wide range of adjustment is provided.
7. PROBLEMS
Speed is way off Maybe the turntable it very un-level. The belt may be on the pulley flange instead of in the pulley.
Check the Pitch Control settings.
No power The power supply plug could be pulled out from the speed box.
Can hear the motor This is normal with DC motors. Should be a very soft purr, almost inaudible at 33.
