Wellington, thanks for detailed info.
Currently I have two RX-5000 tt (also Michell Orb and modded Thechnics SL-1200).
I bougth the two Micro's from Japan (local friend helped me on) so the motors are labeled with 100 VAC.
One of them is supplied by step-down transformer and I didn't touch it the other one is modded a bit, the transformer was re-wounded professionally to 230V, I replaced all electrolytic caps with Elna audio grade, the two trimmers as well, I removed the rust and cleaned the electromotor and I lubricated very slightly the motor shaft.
Both motors are stable and keep the speed well. Generally I measure with iRPM but I can use also 1kHz test LP/osciloscope.
By profession I'm not electrician but I have a bit skill and experience on this area.
I just got inspiration from you to replace the pure DC regulator to a beefy one. So please send me the data if you can find around.
Sometime ago also I was interested in Kyocera and 1500 with air bearing but finally I turned on other way.
Can you compare them to RX-5000?
Thanks a lot and take care!Rerurn to Romy the Cat's Site
