Speed box with the correct power supply and required pulley plus two drive belts. I believe this works with quite a few Project turntables. I used it for a short time on a Project Debut 111 model to good effect. Condition is excellent and boxed. £70 plus posta, collection welcome.
Please not this is the all black case. No difference just an option.
