rega planar 2 slightly fast running

Post by edwar65 » 07 Jan 2020 22:40

Hi.
Done a recent test on my early planar 2 just out of interest,by measuring amount of revolutions in 3 Mins to Establish running speed apparently it should be 100?? Anyhow at the 2.55 mark it's it the 100 revolutions,meaning that's it's fast on 33rpm??
Is there an easy way of correcting this or is it normal for these decks?? I'm in UK it's running at 230v or so not sure of frequency around here??
Thanks

Rega purposely made them a bit fast, so they would sound brighter than the competition.
I suggest a pencil test: remove the platter, rest your hand on the base, and lightly touch the point of a pencil to the side of the rotating sub-platter. Some of the old ones did not age well, and the resulting roughness could affect the sound.
If the test reveals that problem, then a machined metal sub-platter will correct the speed, stabilize the sound, and improve the overall sound. If the sound you are getting is satisfying you now, no problems.
I initially corrected the speed by adding layers of Dymo embossed label tape to the sub-platter. It works.

Cheers,
Alec

Back in the 80s when me and my friends used to copy LPs to cassette tapes it could be noticed that TTs usually ran a bit fast. When you copied an album from cassette to cassette, it obviously took the same amount of tape. But when copying an album from LP to cassette there was usually more tape left. Most of the folks didn't have possibility to adjust the speed so nobody paid any attention to it (or cared).

Similar to my RP1. It runs to 33.75 rpm approx. I solved the problem with a rubber band.

'There's an app for that! ...' called RPM if you fancy digging a bit more!

4 years, same as RP1. I have changed the belt (white rega belt) today and the results, not good still, are:
With new belt: speed without rubber 33.67 rpm, with rubber 33.05 rpm :( :(

With the old belt and the rubber it runs at 33.35 so I wont change.
