Furthermore, beat up DJ-decks that come in for repair really arn't indicative of what the typical SL-1200 has to offer, those units have a hard life. Really, you used a lot of words just to say that the SL-1200 is a design that can be improved upon, it would have been much simpler to say that from the start and I don't disagree. My questions were not related to other Technics-series turntables and while those may provide a level of insight into the relative operation of similar turntables, they arn't the same, and you can only gleam so much.
tl;dr I do agree that the design can be improved upon, but I respectfully disagree with how necessary those mods are, and the measurable level of improvement vs. cost that they actaully provide.
A turntable has advanced well beyond what was ever originally expected of it. The measurements of wow, flutter and rumble do tell the basic picture - if they not at least respectable, it makes no sense improving anything else.
It is the acoustics of the turntable that is far harder to measure, qualify and/or quantify. No official standard available, one can use duplication of past methods by various sources to arrive at anything like comparable result. Most TT manufacturers, not only Technics, never actually made good sounding commercially available TTs. And I will say that for the SP10MK2 as well, despite being far more advanced design than 1210.
The most glaring defect 1210 has, along with countless other turntables, is the power transformer within the deck. It does not belong in the turntable - period. It was and is being used as cost cutting measure. Transformers vibrate and that is being picked up by the cartridge. Any hum, transmitted either as mechanical vibration or electro magnetic interference, will colour the sound. Once you heard it removed, there is no way back.
And this is the first snowball one can start rolling atop snow covered mountain called 1210.
Only fairly recently, say within last 15 years, have manufacturers started to realize the "acoustics" of the turntable in more down to earth priced designs. Project RPM4 may be basic belt driver, but it is not resonant structure as 1210 - either in this or some other models, platter is made from industrial waste like mixture of wood, textiles etc, pressed together and machined as non resonant platter. 1210 platter, even with its plastic/rubbery
insert, rings in comparison badly and for far too long time to allow for the correct reproduction of signal recorded in the groove of the record being played.
Previously, turntables that achieved quiet enough platters have resorted to mass and more mass, being priced out of reach of majority. One turntable that can be regarded as milestone regarding "acoustics" is Townshend's Rock and its later variants - it has spawned a whole bunch of TTs that adressed more or less the same issues.
And I did see DJ and pampered audiophile 1210s - depending on luck how well the bearings of the tonearm have been adjusted at the factory, it can be either to come on top.
