I see many diy turntables on this forum. With millions of Technics SL1200 SL1210 turntables still in use available as a turntable diy project. I do not see anybody using the Technics SL1200 motor, platter, bearing to create a diy turntable???
my mk1
I am building one based on a mk1 motor an platter.
I have made it from hardwood.
The platter is recessed so it is at the exact height for a rega tonearm to drop in.
I have made the strobe too out of acrylic.
It will have a 10mm acrylic in middle that will light up like i do on most of my projects.
I have fully recapped the control pcb

This is where image search shines, as there's certainly no shortage of "custom" 1200's.

MyTechnics - en - calvins-audio-pages . Having looked at the problem I think Calvin was pretty spot on with his implementation.
As technics used the basic SL1200 bearing and motor in many many turntables a donor motor unit can be as low as €10 on ebay. I have mine for when I get through a backlog of other things. My particular interest at the moment is trying a modern uC controlled drive system.

Hi,
thanks Bill.
The second one is in the making, named TheKiller, this time using a Grundig PS-4500 as donor, that is a Technics SL-Q2, apart from a straight arm tube.
The TTs can be tuned with a new plinth and tonearm.
The SL-1200 though having a better plinth than the smaller consumer players.
A new plinth might not be better but just different in optics.
It has been tried to mount top arms on the 1200 with success.
And the arm is not that bad either ..... just the arm tube resonates like a bell and is probabely responsible for a distinct acoustic fingerprint.
And the rubber dampenend counterweight stub mounting doesn't appear the final word on this.
Apart from that the arm does very well.
In fact the bearings are fantastic when adjusted properly and the VTa mechanism is SotA.
I used that gimbal bearing to build my 12" TheKiller Tonearm and achieved just above 160 oscillations in vertical direction.
The platter bearing and electronics of the smaller consumer models don't differ to the 1200.
The higher torque of the 1200 is only due to the higher supply voltage of the motor coils.
For home use the higher torque is of no advantage.
So the consumer models offer more tuning potential at considerable lower cost.
