Sylvania Exponent 4/40 Sound Issues

Yes, the cartridge/needle was a ceramic setup when I got it. Thinking that this was the problem for the distorted sound I purchased a new ceramic combo and got the same results.
This is a early model for the Exponent (1965?). The model number is 4/40-0. The Photofacts show a Astatic ceramic replacement part#. I seen other post that magnetic came along in 1966/67 with model 4/40-2.

If the astatic Sam's for the 4/40-0 mentions is a ceramic look up it's data sheet and compare it's output voltage spec to the spec for the new cart you put in....If the new cart has a higher output voltage it could be overdriving the amp into distortion.
