Vintage DD turntables. Are we living dangerously?


I have just acquired a 32 year old JVC/Victor TT-101 DD turntable after having its lesser brother, the TT-81 for the last year.
TT-101
This is one of the great DD designs made at a time when the giant Japanese electronics companies like Technics, Denon, JVC/Victor and Pioneer could pour millions of dollars into 'flagship' models to 'enhance' their lower range models which often sold in the millions.
Because of their complexity however.......if they malfunction.....parts are 'unobtanium'....and they often cannot be repaired.

Tuchan,
In this case Halcro's table meets Dover's criteria for a closed loop. The loop is closed by the mounting base rather than a plinth or chassis.

Moonglum, No, I have not tried it, yet.
Halcro et al, I only re-stated the case for a rigid connection between tonearm and bearing for the benefit of anyone who is reading this thread for the first time. Such an individual (Thuchan in this case) ought to hear both sides of the question before deciding which direction to choose. Like Henry, I am past trying to convince anyone else who has already made up his mind. But Henry, with all due affection and respect, your analysis of the L07D is ludicrous, certainly compared to the risk for drift of alignment of a fully outboard arm pod. The L07D is a system, using several different metals (stainless steel, alu, brass) with different temperature coefficients of expansion, closely coupled with substantial fasteners and massive. The temperature of a typical listening room varies by a couple of degrees during the course of time. Of course, if you leave your tt in the freezer on off days or cryo-treat the entire unit, you may want to do a re-alignment.
Lew...and this assumes that the feet of an outboard arm pod are even non-flexible and the mounting surface is stable - both dimensionally and mechanically in phase(!) ;^)

The basic frame of the L-07d shown in my attachment is cast aluminium which has twice the expansion co-efficient of steel.
For every centigrade degree change of room temperature (and unless your room is fully air-conditioned 24/7 the variation can easily be 5 degrees C)...there is clearly change in the distance between the spindle and tonearm pivot of several millimetres which is disastrous in the scale of vinyl groove information extraction.
Now please tell me Lew....what is the exact "drift of alignment" of my fully outboard armpods?
