Hi I have a Linn lp12 the motor is probably very old . And in thinking of changing the motor and PSU . Probably a Zeus PSU . Which Linn motor would be best suited to fit
I don't think the motor will be improved by replacement. But the Zeus controller is an improvement. For reference, I have one on an LP12, and have built several others. Let me know if I can answer questions.
Thanks for your reply . The reason I wanted to change the motor was I think it's from 1985 . But after having the Karousel bearing fitted with a genuine Linn belt on 33.3 it takes a couple of seconds to reach the speed but on 45 the green light blinks indicating it's not reached the speed but giving it a hand it reaches the speed taking the outer platter of it's fine so I can only think it's due to the extra weight of the platter the belt is slipping you can tell when it reaches 45 without helping it the suspension judders slightly when the belt grips. I'm not sure what the ans
wer to that is . I did try putting a new Stack Alto serene belt with the same results. But I wanted the Zeus because it's a step in the right direction regarding accurate speed and a big upgrade from the lingo1 I have now

You might try disassembling the motor and clean the bushings. I still doubt a replacement will make a difference.. motors don't get weaker with age unless bearing is very gummed up. Having said that, I think Linn motors are easily found but I have never bought one.
My sondek dates back to 1973 and the motor runs perfectly. It has an upgraded bearing but pre circus. I have the Zeus power controller and also built the external controller designed by Pyramid. I use the Zeus for all in one convenience but the pyramid controller may be better suited to get your motor the extra oomph to get up to speed. It does not have the speed regulation feedback but I built in an external tachometer which allows you to set the desired speed precisely. Happy to share the details if interested but you probably want to explore if it has to do with the karousel upgrade before spending money which might not address the problem.. dB
Thanks dBel84 I've sorted the belt which was slipping when I set the speed to 45 rpm . I'm thinking now of upgrading to a better External power supply but £695 for the Zeus Black external . Can you tell me more about the pyramid supply is it external and and does it come with a new two speed switch and optical sensor . I'm intrigued
Best wishes Neil
The other day I repaired my antique LP12 motor because it was difficult to start at 45RPM. I removed the spring and ball at the bottom of the shaft, and everything returned to normal.
The LP12 motor is rarely damaged. If you think it is broken, you can buy it online according to the part code. Maybe the price is about 60 dollars. There is only one manufacturer of this motor from the UK, but the origin may be different, including the Netherlands and Belgium.
Moreover, the belt is unlikely to slip because the torque required for starting the rotary table is too small. The belt needs only a small amount of friction.
I think you should suspect that there is something wrong with your drive power supply. I have a first generation LINGO that cannot be used at present. I have been trying to repair it, but it has not been successful. There is also a second generation LINGO, which is used normally. Or you can use a 220V to 100V isolation transformer to drive, which will be quieter, that is, 45RPM will be lost.

@Getting100 - here is the link to the DIY pages to get you started SG4
I used a sensor to monitor speed but it does not feedback to control the speed on SG4. DIY Tachyometer
good luck ..dB

Linn made a snap-on cap to replace the spring gadget.
That was a very early update, about the same time as the first suspension spring update.
