Or you were delusional.I spun many a disk on my Planar 2 through the years and never once saw it visibly slow. (Strobe disk attached to a center clamp.)
The belt needs to be changed occasionally and the motor pulley cleaned as well. I'm sure that was your issue.Dave.

What were you using for the cart? I used a Sure micro ridge V15 and changed the belt to make sure it was not the issue.
I was playing the Rachmaninoff 3rd PC with Horowitz and this was at the loud portion near the end of the 1st movement.
I used at V15V-MR and a test record with some worst-case groove modulations.
The problem with those Rega's is the belt slips on the pulley at turn on/off and stretches/wears it fairly quickly. The pulley needs cleaning occasionally as well.
The belt only makes contact with 1/4 of the pulley circumference, so if the belt is marginal and/or the pulley dirty you get slippage. This is most likely what you were experiencing. A simple five-minute cleaning and new belt would have solved your issue.
It's a round cross-section belt in a V-groove so the contact area is minimal.
If you know anybody who wants a Rega Planar 2 with no arm let me know.

I remember the Rega pulley and how hard it could sometimes be to get the "belt" to stay both in the pulley detent and the subplatter channel. But I don't think I was having that problem.
The very loud passages were followed by wow in their reverberant trails, which I also had with the Oracle tables though not to the same extent. After hearing the twang in the Rega after loud passages I started noticing it during the loud passages and after loud whacks on drums and piano poundings. Years later I noticed it on the Oracle table too. It was at a lower level and was a substantial improvement over the Rega but was still there and became more obvious over time.
I had always used clamps on the turntables so I am fairly certain that it was never a matter of slippage. Also this did not occur on the Lenco I had before and I didn't have a clamp for it, I just used a weight occasionally..
Some clamps won't work effectively with those Rega tables since the center post is not securely attached and could rotate relative to the platter and/or pull through the hole in the glass. A weight and/or a "sticky" mat would be the only alternative to prevent slipping between vinyl and glass. My setup was superior in that I used a clamping/weight scheme that didn't exert any upward force on the center post.
Regardless, the belt slipping issue is a separate one.
Dave.
The clamp I used on the Rega is similar to the KAB clamp I use on the Technics. The Delphi and Alexandria have threaded spindles for the screw on clamp and sticky mats. The Oracles also have a wide belt with lots of contact area on the subplatter. One of the reasons I got the Oracle in the first place - to avoid the "twang" issues I had with the Rega on loud transients and loud passages.
