It can but you will need to boost the output voltage & current as follows:

If your motor draws more current/voltage then you will need to use an off board supplementary amplifier as per Pyramid's SG4. This motor controller can be used as a source for the sine waves and to handle the tacho & feedback/control functions.

Hi, Can this unit be used to control a Lenco 75 motor.

Cheers

LP12 alternative switches

For those of you planning to put the Motor controller inside an LP12 you may be interested to know I have located a source of the correct momentary action switches & LED that were used with the Valhalla. I have 3D printed the correct bezel/surround. I will print in black eventually but I only had grey material for the test.

These will only fit the motor controller boards and not the original Valhalla due to the FFC cable I have used. (I am trying to find something compatible with original so they can be used as Valhalla spares).

If you would rather have these rather than the other momentary action types or the optional Linn Valhalla switch connector let me know via a PM and I can change or add to your order. The switches are quite expensive though and I estimated the complete switch/surround/FFC will be in the region of £15-£20 depending on how many orders there are to split the supplier carriage charge reasonably.

Incidentally, I am placing parts & PCB orders this week. Thanks to everyone who has paid their deposit.

External enclosure for Motor Controller

For anyone considering mounting the motor controller externally, this was the way I did it for my Manticore Mantra

I used a Hammond 1455T2201 Extruded Aluminium Enclosure 223 x 160 x 51.5mm Natural.

I mounted a circular connector for input power and motor power. The sensor/switch and OLED cable is a very thin FFC cable so can pass through the rear/side of the case or I have developed a small rectangular panel mount connector PCB so the FPC can be disconnected/reconnected externally. (not in these pictures though).

The PCB is mounted on self adhesive standoffs.

Hope this helps if you do not have space in your plinth.

Hi Zung,

it just suits my setup. My Manticore Mantra has a large illuminated mains power switch which I wanted to use so I used the main turntable feed & switch and sent the power down the circular connector and the motor drive back up.

It's personal preference and your suggestion:

AC -> IEC connector -> Box + board + display -> Round connector ->

is perfectly valid.

I was thinking of producing a 3D printed enclosure which would provide the same.

Any reason why you don't use a more conventional scheme such as:

AC -> IEC connector -> Box + board + display -> Round connector -> Turntable
