I have an audiophile cs-503 vinyl player, and I'm having a hard time manually calibrating its speed.
I'm wondering if there's something I can make, to do it properly for me?
This model uses a hex key screw underneath to change the resistance(?) on the motor to speed it up or slow it down. My manual methods have been by ear or using a mobile phone sat on the turntable and adjusting the screw, with variable results.
Open to options.
