TT, 12" Tonearm. Who tried and ended up preferring 12" arm?

Elliott.
Sounds like you are doing your homework and due diligence, very commendable.
I did see that one on Audiomart and it does look to be in nice shape and includes a step down transformer ( even though he says step up, lol)

Unfortunately some of the items exported from Japan can show some corrosion due to the high humidity and if they have been stored in a warehouse or store room for some time. You do have to be careful.

Yes rubber does degrade in the enviroment due to chemicals and reactions to such , unless you live in a clean room that is!

And yes that two arm base IS HUGE and heavy! I only just squeezed it into the space the TT-71 had been with barely mm to spare. I do not know if the smaller single arm base is constructed in the same fashion though.

Good luck if you decide to pull the trigger on the Audiomart item!

This is an old listing for the single arm plinth, very hard to tell from the pictures the exact construction though.

And this quote from The Vintageknob on the ql7

"Victor’s CL-P bases are made of four layers of high-density particle boards and three layers of special inorganic material ; I don’t know if that structure was retained for the export black base"

However not sure the total accuracy there.

Just a final comment on the droop seen on many 7082 and 7045 arms.
The only way I believe you will ever see one of these with zero droop is from a nos example that has lived in its sealed box all of its life.
Many reasons for the droop to exist on used examples.

Not really, the NOS are normally very expensive compared to gently used samples, just like everything in audio. I've seen only a few NOS samples in 5 years or so, i bought one of them, it was 7045, sold it when i bought long 7082 (used). My 7082 does not have any problem with rubber grommet, but it's original, everything is clean like new. 

Regarding the used 7045 only 1 out of 3 wasn't perfect. So it's possible to find a perfect used sample, nice and clean. 

Another problem is oil in armlift, but the whole armlift can be replaced with new jelco armlift.

The problem is that most people selling junk on ebay, i prefer to buy everything from a perfectionists like myself.  

Chak, I am looking at your post of 12/22 at 12:06.  Do you not see a slight sag in the CW, even for your pristine example?  I do.

C'mon now Lewm.
Chakster is always right and has to have the last word......
