Order the stylus that matches the cartridge in the headshell. Do not order Sony ND-126GA because the cabinet says Sony. This stereo was bought as an HP-511A and turned out to be an HP-510A. The two all-in-ones look like siblings. The needles are not the same part.
The ND-126GA is the stylus Sony fitted to the HP-511A. Replacements sold for the HP-510A are a different shape, specified to track at 2.0 to 3.0 grams. A listing that names both models is covering its bets. Compare the cantilever and the mount you can see on yours with the photo on the specialist's page. If they differ, you have a cartridge someone swapped in since the 1970s, and the model on the wood does not pick the needle.
There is no Amazon link on this page. These styli are a specialist part, and an unmarked marketplace needle is the usual way to get a tip that will not sit in the cartridge or that chews a record. Buy from a stylus house that shows the mount.
Which number is which
| Cabinet | Stylus people paste into listings | What to match instead |
|---|---|---|
| HP-511A | Sony ND-126GA | That number, if the mount in the headshell agrees |
| HP-510A | Not the ND-126GA | The 2.0 to 3.0 gram replacement whose photo matches yours |
| Either, cartridge already swapped | Either number, wrongly | The stylus body you can see, not the badge |
When you do not need one
Hearing the record in the cartridge is needle talk. The diamond is reading the groove. Silence from the speakers is a clip, a switch, or the amplifier, and a new needle will not move that signal. The first pass is the crackle guide.
If the tip is genuinely gone, set tracking force to the range printed for the stylus you received, not to a number borrowed from the other model. Too light skips. Too heavy, on a conical tip past its range, eats the groove. The four clips behind the cartridge go back on the same pins they came off. Color for color, and a clip left in the well is a dead channel on a brand new needle.
