Hi Wellington,
I have rebuilt the other table after living with both for several months of comparison. The oil comparisons were done over several months as well, granted the differences in oil viscosity well smaller compared to the other changes. The main differences was that speed stability was improved over the stock bearing, and turntable came up to speed much sooner. Some of the speed problem was also due to dried out electrolytic's. The biggest improvement came with the stainless steel platter(heavier) and copper mat.
Hi Measet,
Basically the modification to the power supply would be
a) Outboard DC supply with a toroidial transformer , filtering and pre-regulator.
b) Second regulator inside the motor unit.
c) Possible tuning of the servo circuit driving the motor.
The bearing rebuild is not really that hard and I have rebuilt three RX-5000 bearings and four RX-1500 bearings.
Note. The RX-1500 Air uses grease for bearing lube because because regular oil would clog up the air passage.
Nice looking cat, by the way.Rerurn to Romy the Cat's Site
