For almost a year I have a vintage turntable from Perpetuum Ebner at home.
It's not mine. It belongs to someone that asked me to fix it. And it turned out that fixing the motor would cost too much.
I asked the owner to collect the tt. That hasn't happened yet and the machine is collecting dust at my home.
So I'll take the freedom to attempt a non-intrusive repair with modern components. I'm also thinking about making it an Enchanted Object.
Perpetuum Ebner was a Turntable factory from the Black Forest. The founder was part of the same family that started Dual. Both were located in the same area and produced classic designs. The model that I'm hacking here is the PE Musical 1 from 1958. The history of the PE company is well documented on the internet. |
The main focus will be to get a new motor. There are only a few criteria: it has to run smooth and silent and needs to be able to run for a long time.
I'll need to build in a motor controller and a tachometer. I'll have to provide the control logic to keep the speed constant - doing very slow adjustment when needed.
I am also thinking about adding functionality. I can measure and publish statistics on its use. I may even be able to stream the audio.
That is the idea that I'm playing with most: make it an audio server for a wireless home music network.
I'll post progress on the @element14 blog. I can use help on choosing a good silent motor.
As a sad side note: the failed 'traditional' repair attempt:
