UPDATE: I now know for sure that what my problem was as far as no audio goes was indeed that I had accidentally ordered the wrong needle.

The original needle was an ASTATIC 99-1 Needle which is a 1 mil sapphire tip needle for use with 16, 33, and 45 RPM Records of Microgroove vairety which that needle has the hot contact on the left side of the needle and the ground contact is a plug like contact that is on the base of the rear of the needle.

The one I ordered thinking it was the same as the original and not paying attention to the drawing of how the contacts were done or the model number on the original needle, was an ASTATIC 101D needle equivalent which has both contacts on either side of the needle which is why it didn't work and why I didn't get any audio.

But when I touched a screwdriver to the ground contact inside the "cartridge" the record player made a loud and pronounced humming noise like it was supposed to, the reason why it didn't make a loud humming noise when I tried it previously was because I was accidentally "grounding" the ground contact to the housing of the "cartridge" which essentially neutralized any hum being induced by my touching of the ground contact because it was basically functioning as if the needle was inserted inside the "Cartridge".

So it seems that my next step is to order the correct needle for this unit and I should be all set.
