Vintage DD turntables. Are we living dangerously?

I am only going by what vintage knob has to say. I can't swear to how truthful their statement is. It's obviously an opinion but justified by the evidence presented.

"The TT-801 is an extra-rare LP drive and the culmination of the well received but earlier TT-101.
The engineering and bi-directional dual FG servo are the same, even if implemented more discreetely as 1981 allowed more ICs and chips - which isn't necessarily better for long-term servicing."

As far as the vacuum system:
"The Turbo Disc Stabilizer System isn't that different from the one used by Luxman/Micro, but the latter allowed to put the main bearing much closer to the spindle.
The complete system consisted of the TT-801 drive, the TS-1 air pump (optional) and CL-P10 base, with blank or pre-drilled CL-P1D, CL-P2D and CL-P3D armboards."
However, the TS-1 could be adapted to the QL-A95 integrated turntable.
Since the Victor TT-801 was never exported, it never was named JVC TT-801 but only Victor TT-801.

The 801 looks different than the 101 also.

You certainly could be correct on the TT801. I read that blurb on Vintage Knob too, earlier today.  The TT801 wouldn't interest me purely for the vacuum hold-down, but the idea that it might be different from the TT101 in other ways, most notably because it has a higher mass platter, is quite interesting.

I sent a TT101-specific Integrated Circuit chip to a fellow enthusiast in Germany for repair of his own TT101, and he informed me that my chip worked to salvage his unit.

Thankfully I remembered that Lew had 'cornered the market' for the only unobtanium chips used in the TT-101....so after 6 months of stalled frustration......Thuchan's 'junk' TT-101 which I had found for him, is now operational.
And after the complete re-build which his Bavarian craftsman has performed.....it may well be the best TT-101 in existence.
I've offered to buy it from him should he not like it...👅🎼

Maybe this is the one for you Halcro?

That TT-801 on Yahoo Japan looks in fine nick Banquo....although it doesn't have the original pressure-seal mat.
That Victor TS-1 air supply also on Yahoo Japan would be a risk Dover as the Seller hasn't tested its operation and is advertising it 'as junk'...😢

Interesting points about the differences between the 101 and 801 Banquo...and as Lew says.....the differing platter weights and chassis weights are intriguing.
Is this even BETTER than the TT-101?
