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.

I have had a few weeks now to assess the effects of the Krebs mods on my SP10 Mk3. I was kind of a reluctant dragon going into this endeavor, because I was very happy with the Mk3 "as is" (now "as was"). When listening to the Mk3, I did not really perceive the kind of issues or colorations that were supposed to be "fixed" by the Krebs approach. This is in contrast to my experience with the SP10 Mk2, now departed. I could easily hear the "gray"-ish coloration that Richard perceives to be caused by an over-active servo (for want of a better way to describe it), when listening to my Mk2. In any case, you have to hear a modified Mk3 in order to know what you were missing. Richard's work makes the Mk3 more open and musical sounding, more of what HP used to call "continuousness". Based on this experience, I would suggest that the Krebs mod is also a no-brainer for the much more common Mk2. The cost is modest (especially for the Mk2 mod) compared to the benefits. Thanks, Richard.

I encouraged Richard to consider developing a modestly priced modification for the SL1200 servo and motor, since there are thousands of them in every day use. Apparently, he is already at work on that.
Henry convinced me going for a 101. my unit will arrive in about 2 weeks and I hope it has not too many defects as it is "for repair". I got a lot of information from Henry (👍 many thanks) also preparing my service team which is ready to start 🔧. now I am collecting ideas what kind of armpods I should use? Henry's pods look very nice and stable. I 'd like bringing in at least four arms on the DD, also an EA-10 which has a huge counter weight below of the arm. Therefore I need space below of the armboard.
If you are soliciting opinions from anyone with an opinion, then here is mine. It is a great idea to have a massive arm pod, and Henry has done a fine job design ing and constructing his. I could never do as well. However, the arm pod should be firmly physically attached to the same structure that supports the turntable bearing, so that the two are as close to being one as is possible. The arm pod should not stand alone.

Take a look at the arm mount and the underside of a Kenwood L07D, if you want to get an idea of how this can be done.
Thanks Lewm. What is the disadvantage of stand alone armpods and why is it crucial that there is a connection between armpod and table? Does the physical connection bear any advantages?

Taking Henry's excellent implementation, would it help if the separate armpods are standing on a firm platform as well as the 101 or would you propose a touch to touch connection between armpods and table?

I have seen the Kenwood's realisation. Very well done!
Just imagine one would take a non-plinth integrated 101 how could you connect pods with the table?

This subject was a bone of contention here previously with the Train
analogy front and center. I will leave it at that.
