Rega RB300 tonearm with original wiring loom, with counterweight and mounting nut. In Rega service box. Unit has been in storage for the past 10 years. Some oxidation on the cartridge leads, traces on tonearm from mounting a previous cartridge. Wiring loom tested for continuity. Anti-skating works. Tracking weight setting works, while it was in storage it was set to 3g to take away the stress on the spring (see literature). Bearings are fine. Although the arm has not been used for at least 10 years I assume it is in working condition. I did all the visual tests you can do on a not mounted tonearm. More information can be found on vinylengine. As with the RB250 this arm has been tweaked by users or oems in various ways, most of the time changing the wiring loom,... This is the plain version as sold by Rega without any upgrades, tweaks. Service history: Tonearm had a new wiring loom at Rega UK in 2005. Shipping signed for and ensured.
