Before you invest in a push tune, try the shim (if you can). I had my RP23 push tuned at a cost of £200 (inc a new sleeve). Its only a little better than it was with just the shim – not bad considering I hadnt touched it in the previous 2 years.
The shim can be a good change, but it’s very different to the Push upgrade. A damper upgrade is never going to be able to cure a falling spring rate for example.
Superfli – Did the CD case not snap, it feels like it would? Assume we are taking about a standard case?
I assume he means the type of case you get on a spindle of CDRs, not your Spice Girls album. 🙂
