Thank you David. Thats what I thought, but unfortunately mine was lost somehow when I took my system totally apart to renovate my room. I have to buy A new one.
I've always wanted to try an SPU cartridge, but I don't know which extra counterweight to use for my arm. Should I use the 64 gram or 77 gram additional counterweight. Any help will be very appreciative as I have to either find one on the used market or have one made.
