A&R (Arcam) P77 Stereo Pickup Cartridge
The A&R P77 is a mid 1980s vintage moving magnet high compliance cartridge designed in the UK by A&R Cambridge and manufactured in Japan to very exacting standards. The cartridge may be viewed on this site here.
The P77 featured a Weinz Paroc (parabolic oval cone) stylus on an aluminium cantilever, and was noted for its warm musicality and punchy output. It became a very popular cartridge due to its ability to work well in a wide range of tonearms from budget level to the more expensive. Although now long out of production, the cartridge is still much sought after today, a testament to both its lasting musical capability and good build quality.
At 6 grams, this is a medium mass cartridge.
