Hello, I am new here. Maybe someone have an answer for this problem I have. I have a very nice Oracle Delphi MK IV. Not upgraded. I am having problems with the speed. I can't get it to go at the right speed. It is too slow. Using the adjustments do change the speed but not up to the correct one. Any ideas? Maybe I need a new motor. Or the upgrade.
Many thanks,
Eric

Hi Eric Sisi,
Check your Power supply (Wall wart if you have one) voltage.
If it varies to much a few volts than try a otherone.
Make shure it's AC or if you have a DC PSU check polarity.
All the best.

Describe the problem in more detail, for example history,
and give some more info about the motor and how the
speed is adjusted.
May be able to help, or make some suggestions, 🙂 /sreten.

Check out this thread: I used to have the same problem!

It's an old thread but compared to the mk IV it's quite recent ;-)
Anybody know how the speed control actually operates?
The motor is Berger Lahr 50/8 (?)
On the main circuit board is a wien bridge oscillator with separate adjustment for 33 1/3 and 45 rpm. There is another common adjustment on the (tiny) operating board and this controls the run / speed / stop functions, it's somehow giving a signal to the oscillator.
Looking for possibility to improve speed stability.
