Need to adjust the speed every time I turn on turntable


Need to adjust the speed every time I turn on turntable.This is a belt driven Oracle Delphi II with Origin Live motor and Origin Live Control Board and Origin Live Power Supply.  I am guessing it can be the belt, motor, control board and /or power supply.   How do I determine what is not working?

Humans tend to confuse experience with reality. The human mind is designed for this as a modus operandi. A simple statement about a complex scenario, it is....

Hence the grating, constant, and unstoppable nature of forum arguments.
Agree, teo. We also tend to draw false relationships between a list of causes and a list of effects with no real data to support a connection of one to the other. But it makes us feel good to have a pat explanation in hand.
Found an interesting site that shows the entire North American grid in real time and the deviations as they occur. The bar graph above the map goes from 59.940 to 60.060 Hz and is color coded to the map. It changes more rapidly that I thought it could but not enough to cause us concern.

Type in FNET/Grideye

Well, that link doesn't seem to work, just type in FNET and look for FNET Server Web Display. US Frequency Gradient Map on the top bar will show you the display in real time.

Update for interested parties.  The issue was multiple items  1.  Replaced the caps on the power board.  2.  Issues with the variable resistors to set the speed.  I may have pushed them down as I adjusted the speed frequently.  3.  Belt.  The standard Oracle belt did not work well with the Origin Live motor.  There a Oracle belts from Origin Live.  Things are looking brighter.
