I also bought one of these JVC L-FX4 turntables for $12.00 today.The base is cracked on the tonearm back side and the needle is missing from the Audio Technica model # AT403EP cartridge. Have you found any helpful information as of yet? I'm wondering how one goes about adjusting the tonearm tracking weight, or does one have to find a P-mount cartridge that weighs a certain weight? I'm lacking any good understanding about P-mount turntables.A while back I bought a Technics SL-QD33 that cost $15.00 plus the shop charge of $50.00 to fix the platter speed problem. At least it came with a usable P-mount cartridge. The down side with this Technics turntable is the cuing action, it drops rather fast and manual cuing stands are rarer than chicken lips to find anywhere! Please write back to me if you have any ideas or comments.
