In brief, here's how you calibrate a straight arm turntable.
- Tiny Phillips Screwdriver (this comes with the headshells for free)
- Steady Hand
- Reading Glasses (if you are really old)
- Diamond Shaped Needles (Preferably the Shure N44-7 since it's almost bulletproof)
IMPORTANT: With the following steps, you must be EXACT with your angle or you will cause damage to your records or they will sound funny. Do not settle for "close enough" measurements or your records will skip or sound funny. If your records skip, fine tune your calibrations right away, or the needles and\or records will wear down prematurely. (New needles are ideal for this situation since they need to be broken in anyway.)
Measure from the back of the headshell slot to the start of the mounting screw when adjusting. (as shown above) There is little forgiveness in the sound quality if you are too far forward or back.
Once on point, tighten down the headshell mounting screws tightly, slide in the diamond shaped needles, (N44-7) mount the stylus on the tone arm, and you are done! Now get your scratch on!
