Hi and thanks for your replies and the welcome.
With such fast and detailed responses I'll need to get organized so that I can ask solid questions.
I have had my Music Master for about 2 years. It has lost the nameplate and I was told it was a NEAT when I bought it. Checking the web I decided that prob was not correct, but I didn't find this thread or much else at the time and am know just finding much better info.
I love its heavy and uncomplicated build and I won't part with it. I'm definitely in the category of 'love audio, love vinyl, love old gear, can't spend much $$' so am enjoy budget improvements done when I can find something cheap or make it myself. I've cleaned up the Musicmaster and made a temporary plinth from old pine table-tops. I intend to build a constrained-layer plinth and couple the top-plate to it. Acos GST-1 arm and Ortofon 2M Red. I have double stacked rubber platter mats from a Technics SL1700 and a HKardon, as they were the best I had in my collection. From what I can hear I'm sure there is a lot more to be gained from servicing and improving the set-up.
Mine does have the oil tubes. I did enjoy pulling the motor apart. It's a good old beast! I hear a fair bit of rumble but it looks like everything is the old original so am not surprised. But it still sounds much better than my Dual 1219. Can I ask where you bought a new idler wheel? I'd like to replace mine to see how it sounds. I'd also like to replace the motor mounting bushes if I can find an alternative.
The platter is lighter than the build of the top-plate & motor. It would be nice to machine a new heavier platter & bearing
