I bought my Rega Planar 3 back in 1980.
I was in my early 20's and just getting into home audio.
At the time the Linn Sondek LP 12 was all the rage ... but that was out of my price range.
Then I happened to find a second hand Planar 3 for a great price that had never been used and never had an arm fitted.
I bought the planar 3 and took it to a HiFi shop that recomended I fit a Stax Unipivot arm to it.
However I was never really happy with the Stax arm so when the RB300 arm was released I bought one and fitted it with an Audio Technica AT32 MC cartridge.
I then upgraded the Audio Technica to an Ortofon SPU MC and have had this same combination for the past 28 years.
Earlier this year the motor speed had started becoming eratic (suspect the capacitor was failing).
So I replaced the motor with the 24V Synchronous Upgrade kit and it was back playing sweet music.
I have plans to upgrade the sub platter & platter later this year and maybe add the TT PSU as well to finish it all off.
My Planar 3 is now over 30 years old and I'm still very happy with it.
