pink triangle turntable - little pink thing lpt
 |
First of all a comment from an owner - " a quick note to say
how astonished and delighted I am with the performance of the Origin
Live dc motor that you supplied and fitted to my pink triangle
turntable
'little pink thing lpt'. For once the journalistic hype is true,
the sound of records played on the pink triangle deck with the
OL
motor is phenomenal. Bass is extended and cleaner with fantastic
definition, midrange is wonderfully open and the airyness fo the
treble lets the listener into the whole recording acoustic. Anyone
who hasn't fitted your dc motor and is still wondering how to
get
the best from their records should do so straight away. It is such
an incredible bargain at £339 that I am left wondering what
took me so long!" |
OUTLINE - The existing motor plate is replaced by an
Origin Live motor plate and mounted level with the top of the pink triangle
turntable plinth. The MDF baseboard needs the motor hole enlarging to
allow the motor to protrude from the bottom of the deck - it also needs
a 1 x 4.5mm dia hole drilled to re-site the motor plate support bolt.
PROCEEDURE
1. Undo nut on the underside of the platter bearing - long nose
pliers will do if you don't have a socket spanner. Lift topboard off to
expose turntable base board and motor as shown below - Lift out motor
- it pulls out with the 3 rubber mounts which are just tight fitting not
screwed or attached in any way.
2. Enlarge hole for motor in baseboard to approx 40mm diameter to allow the motor to be fitted - the motor is best not attached to the topboard if you want minimal noise through the speakers. I found drilling the hole easiest by drilling a 3mm hole through from the top and then going through with a 1.5" fluted cutter from the underside with plinth turned upside down.
3. Drill 5.5 dia hole for M5 machine screw - position the motor plate (with motor attached) and mark the 5.5mm hole position as shown on photos below. Ensure the pivot bolt hole is positioned on the radius line 90mm from platter bearing centre - this avoids the M5 pivot bolt fouling the platter and belt. Also ensure that the motor is clear of baseboard hole and free to swing to allow belt tension adjustment.
4. Fit the M5 bolt with a large washer under the base board - next fit the M6 then M5 brass washers - then thread on the M5 nut to clamp these to the base board.
5. Using 2 M5 nuts and 2 M5 washers clamp the motor plate at the correct height - i.e. the top of the motor plate is level with the top of the plinth. If you tighten this to a reasonable tension you can swivel the motor to give the correct tension and it will hold in place by friction.

Before drilling the 5.5mm hole for the motor pivot machine screw - note that it must be positioned to avoid fouling the platter. |
View of motor fitted using round motor top plate supplied by Origin Live - height is set by clamping nuts on either side of motor plate. |
Motor power wires are clamped in position using large washer and screw. This prevents straining the soldered joints on motor.
