33.3 and 45rpm speeds are very accurate and make a significant improvement to sound quality. This unit has well under 150hrs use and is in full working order and excellent condition. Comes in its original box. You need to be comfortable with fitting it to your LP12 or if not take it to your trusted local dealer. Instructions for fitting can be downloaded from a supplied link. Steve at Valhalla Electronics is very helpful if required. Will send by RM in original box. Any questions please ask. Sale only, no exceptions!
