BAS-S Phonograph needle. Used In RCA Victor, Victrola And Many Other Record Players With A Cartridge That Uses A Set Screw Or Thumb Screw To Hold The Needle In. This Needle Can Be Used In Wind-Up Victrolas, But Pressure Force Could Ruin The Tip, So Care Must Be Used. It Will Not Last As Long As It Would If Used For The Electric Victrolas But Still A Vast Improvement Over Steel Needles. Tip: 3 Mil Synthetic Sapphire Tip. Speeds: 78 RPM. New.
Steel Needles Are Very Hard On Your Records. One Or Two Plays And Already They Are Worn Down And Begin Damaging Records. Sapphire Tips Will Last 80 To 100 Hours Of Play With Minimal Damage To Your Records Under Normal Playing Circumstances. This Needle Will Give You The Best Sound Your Player Can Produce.
