Since 1990, I have enjoyed collecting and restoring antique radios and vintage audio.... all items I list will be exactly as described and packed extra well to ensure a safe delivery.. buy with confidence ! Ask any and all questions BEFORE buying! For sale is a COUNTERWEIGHT that was removed from a PL-115D turntable. Same part (PXA-599) was originally supplied with the PL-112D and PL-117D, and probably many others. Based on my research it should have been same part used on the PL-510, PL-530, PL-550 and PL-570 and others. In excellent working and cosmetic shape... all lettering is very clear and readable. BUYER is responsible for doing their own research to ensure they are buying the correct part (s) for their turntable/audio application. NO ORDER CANCELLATIONS or RETURNS for any reason ! NOTE: Best way to check if this part is the same part used in other models is to find/download the SERVICE MANUAL for the other model, and compare the part #s for the other Pioneer model to part # PXA-599 for this PL-115D model. Will be packed very well to ensure a safe delivery! Ask any and all questions BEFORE buying! After buyer has left positive feedback to acknowledge everything OK, I will immediately return the favor.
