Re: Help with turntable motor control board

I really haven't looked at the Axis motor control board, but if memory serves me it was attached right to the motor itself. I would suspect that there has to be some level of adjustment and those pots are it. An ociliscope would be the way to find out and dial them in correctly.

Your other option would be to bypass that board all together and put in something more reliable and potentially better sounding. When I used to sell Linn we saw a lot of Axis tables with failed motor control boards. I would suspect that a viable alternative and one that could be easily retrofit would be a used Valhalla board or for that matter a Basik or Lingo. Also there are a number of DIY power supplies based on the Naim Armageddon that work really well like:

Now I don't know because I'm assuming that like most linn products this motor is basically the same and just looking for a 50 Hz signal to generate 33 RPM. I know the pulley was different sized than either the 50 or 60 Hz LP12 but so was the innter platter diameter.
