I have a new Record player needle. I realise there are 4 pins they come from 2 coils within the needle 2 of the pins are negative and the other 2 are positive how can I tell which one is which.
Just to explain further, the original 78 records had much bigger grooves, as did the very early LP's - then the technology improved enough to create 'micro-grooves' which were much smaller, and LP's and 45's then used micro-grooves instead (allowing longer playing times). So you needed a different sized stylus to play 78's and the later micro-groove records.Basic piezo cartridges often have a reversible stylus that can be set for LP or 78 tip by flipping the lever. The lever unclips from under the string to remove / replace the stylus. The one in this photo has the shipping cover on it, hiding the stylus tip.
