this page is meant to be a collection of miscellaneous information that i've learned or found, but that was very hard to search for (e.g. google) online. hopefully search engines will index this page and it'll help some people.

these are my normal headphones (purchased circa 2018). the cable broke after about 4 years of continuous use, due to the plastic sheath hardening.
to replace the cable, i disassembled the can with the line-in on it (lots of online tutorials for this) and found that my model had wire colors that didn't match the OEM replacement cable. the OEM cable had red, black, and white, while the board inside the can had copper, red, and blue.
here is the appropriate mapping (which wires should replace which when soldering):
|headphone wire color||OEM wire color|

the Windows codesigning format ("Authenticode") is strangely hard to Google, apart from high-level official technical documentation. this is my collection of official and unofficial technical sources for it.

many sources online imply that the Beogram RX2 doesn't have an adjustable antiskate mechanism, and that the arm's counterweight is the only adjustable mechanism.
this is not true: the antiskate mechanism is adjustable using a dial that's (inconveniently) placed at the bottom of the record player. it has three settings: MMC 1-2, MMC 3-4, and MMC 5. the correct one to use is the one that matches your needle (or for SoundSmith SMMC replacement).
to adjust the antiskate, do the following:
do not be tempted to try and use the thin plastic "indicator" tab next to the antiskate mechanism to turn it. you will snap the tab off. this doesn't break the mechanism, but it does make it slightly more difficult to read the player's current setting.
this is also documented in the Beogram RX2's official user manual (under point 14).
