Ron,

Thanks for the response. I do suspect the crystal cartridge and was planning on having west-techservices rebuild it. When I run my finger over the needle I do hear a scratching noise, but again it is real faint. I am not sure the cartridge is the original since it was glued into the tone arm with silicone and is designed to flip over. The number I see on the cartridge is Astatic 66-T5 or 56-T5, do you know what the original cartridge should be? I do have a couple of erly 40's 78rpm phonographs that do have good cartridges and work, can I use them to provide a signal to troubleshoot or just hook up my signal generator to the leads.
