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.

Gentlemen,  A few question's here,  I have seen video's of this funny looking cart on the technics sl-1600mk2, it looks like a concord plane, very long and angles down on the end,  ok,  everyone laugh again,  what's this cartridge called?, can all turntable's use this cartridge?, it seems to have great treble detail to the sound on these videos, also,  what is all of your opinion's for a cartridge and needle for the 1600mk2? I have some sort of collector adc cartridge that I was considering buying the best contact Japanese needle for,  quite expensive,  however,  I was told by a online shop that by doing so,  this would make this adc the flagship,  since that's all adc ever did was improve the needle's going up the cart food chain,  adc seems to be doing another industry now,  no longer making cartridge's. 
@audiolabyrinth not sure which video are you talking about, but i hope you already checked Ortofon Concorde or Tonar Banana. Those cartridges are nothing special, i would say they are very bad cartridges in terms of sound quality. It’s a nonsence to judge the quality of the cartridge by watching the video. If you want Ortofon look for M20FL Super. Which ADC you’re talking about? They are many ADC carts and they are way different from each other, made by different designers etc. For example the ADC TRX made by Nakatsuka-San of ZYX and this model is way different from conventional ADCs. You’re talking about JICO SAS replacements? I owned several ADC cartridges (including the ADC Astrion) and was not impressed at all. You’d better look for Grace F-9F (Shibata/Discrete-4) or Stanton 881 (Stereohedron) and higher. As for the Technics look for rare SP-20 model, it’s cheaper than SP-10mk2.

I’m not so sure about that. I removed the stock switch box from under my PD444 and substituted a thick, dense wenge wood subplinth that projects forward as a subplinth for a third tonearm mounted to a Micro Seiki brass tonearm board. The big surprise is that SQ was improved for the other two arms mounted to the stock tracks. The subplinth must be acting as a sink for vibration.

I know some people replaced stock feets, but for me LUX 444 works fine in stock condition, i like it better than my SP10mk2. I wouldn’t add 3rd tonearm as i have two LUX PD444, so already 4 tonearms :) However, i’d love to replace side pannels usign some nice wood.

Do you have a picture of your modified 444 ? 

There are a couple of photos of the modded PD444 on my system page:

I replaced the stock feet with machined brass towers and Stillpoints Ultra 5s-- with a fifth U5 under the motor housing.  My 444 came to me with one foot missing-- in all honesty I never heard it with the stock elastomer footers.  I do love this table, and put it at the same level as my L07D.  I also substituted a 4mm TT Weights copper platter mat for the stock rubber mat on the 444.  That was an improvement.
