Tonearm mount on the plinth or on Pillar ?

Chris, thanks for the update on your SP-10 Mk 2.  Your idea to mount your arm on a separate pillar and then bolt the pillar to the base (plinth), same as for the motor unit, is similar to the direction I've moved.  That is sort of a "middle ground" between a naked table and one that is directly connected. ;^)

My thinking is by not mounting the arm and motor unit to the same top layer of whatever material in the plinth but still have a fixed connection, any energy transfer between the two will need to travel a greater distance and (likely) through different materials, and thus be absorbed or at least diminished.  Now after multiple false starts I need to find someone local with the proper tools to build it for me.

I’ve seen many arm pods, but this one ( TH-100) is the most exotic solution along with this heavy TM-10 metal plinth by JoJo Toho Machine (i know nothing about this company).

It’s called Toho Player base System for Technics SP-10mk2, also for Victor and Denon turntables.

This design looks as solid as Neumann cutting machine imho.

I wish i could get time machine to buy this Toho Base for my SP10
There is one for Halcro’s Victor table too (more elegant than naked victor imho)

How do you like it ?

Chakster, that Toho stuff looks very nice.  Do you know anything about cost and who sells it?

Lewn, it looks very attractive, i’m afraid this is vintage advertising.

There is only phone number on the poster!
Someone should call TEL/ (03) 908-0320 :))
Who can read/speak japanese?

Prices for Toho Player base Systems:

TM-10 (Technics) plinth weight 27kg, price 230 000 Yen
+TH-100 Arm base weight 5.9kg , price 88 000 Yen
and something called M-3, m4, m5, g23, g30, g41
(additional armboard?) starts from 12 000  to 68 000 Yen!

TC-20 (Denon) plinth weight 29kg, price 230 000 Yen
TV-30 (Victor) plinth weight 24kg, price 210 000 Yen
+TH-80 Arm base weight 7.6kg , price 33 000 Yen
and p23, p30, p41 (additional armboards?) for 6 800 Yen

If it was made in the 80s then the price is tough!

In a typical cutting lathe is the cutting arm mounted on the same plinth as the platter or is it on a platform ?

The lathe platter and the cutter are mounted rigidly in the same assembly. Ours is made of cast-machined stainless! That assembly in turn resides on an anti-vibration platform which in turn rests on a table with adjustable pointed feet.

By having the cutter and platter rigidly coupled, vibration entering the system does not get cut onto the LP. The same principle must be applied in playback to insure a lack of coloration. Any deviation from this formula will result in -wait for it- deviation (of the stylus) and will result in coloration.

Whether that coloration is heard and accepted as such by the operator is another matter entirely!
