The AT91B Straight Arm Plug-n-spin Kit is an ideal solution for your empty straight type tonearm. You will receive a complete solution that is ready to fit most turntables with what is commonly known as a 'Straight-Japanese' tonearm. This type of tonearm is usually found in Japanese Imports like JVC,
Sansui, & Kenwood. As pictured above this type of straight tonearm is not linear tracking but instead pivots from the right rear corner of the deck. It requires an empty
socket at the front end of the tonearm. The tonearm socket must be .320
inches in diameter, have four pins in the socket, and a single TOP mounted set screw that secures the head shell in the tonearm tocket.
The cartridge is made by Audio Technica & the headshell is a Genuine ADC LMH-1. The needle depends on what you choose above. The cartridge and headshell come pre-assembled.
Once installed, how do I adjust tracking pressure and anti skate?
If you are lucky enough to have these two adjustments, move tracking force counter weight until the needle hovers perfectly balanced above the record. Now rotate the dial with numbers (not the weight itself) to zero. (this is zero grams pressure on record) then rotate weight AND numbers together to the recommended tracking pressure for your needle. Then rotate anti skate to have a setting of equal value. Basically you want the least amount of needle pressure pushing down on the record as possible without it skipping or sounding bad. That will give you the longest life from your needle and records.
NOTE: Anti skate is adjusting side to side pressure WITHIN GROOVE of record. Tracking pressure is how hard the needle is pushing down inside the groove.
