With regard to 'How fast to get to correct speed' These are my steps:
- Hand spin the flywheel first
- Hand rotate the platter until the Tach reads around 33rpm
- Start the motor
- Speed will be within 2-3% straight away
- Due to the PSU altering the voltage, until the tach feedbacks a constant 33.3XX I would estimate it is around 2-3 mins ...it will then be a constant 33.3xx, then a few more minutes for 33.33x, i don't always achieve a constant 33.333 . However, without the flywheel a constant 33.333 is maintained. I only use this deck for 33.3 rpm records, I have a KABUSA Technics 1200 for 45 rpm.
Before i had the tach and PSU shoe-horned into the controller I just used the tach ...at least that way I could monitor the speed of the platter. Without a tach, trying to set the flywheel up and the controller is a nightmare ...or it was in my case anyway.Hope this helps.Rerurn to Romy the Cat's Site
