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

@elliottbnewcombjr

They TVK are wrong/misleading regarding the TT-71
it is not Bi-directional nor coreless. 

A lot of what has been said is true the TT-81 is a very good TT.

There in my mind still exists some questions as to its design
similarity to the TT-101 although many statements have been made.
I'll leave it at that since I can't definitely prove it.

totem395,

you are correct, this is the proper link for TT81 and TT71,

http://www.thevintageknob.org/jvc-TT-81.html

the TT101 page

http://www.thevintageknob.org/jvc-TT-101.html

there are specific differences between 101, 81, and 71, which, after it gets going, or method of braking, really doesn't effect playing. the oil/spring/damping solutions seem to vary a spec also.
..........................
as for the pre-packaged units, I gather:

QL-10 and QL-F6 both had the TT101 motor, the QL-7 had the TT71 motor. Some mention of QL-F6 also having ....
deck construction of those ......

QL-F6

i'm glad lewm and others led me to finding more about these.

you have a lot of beautiful toys, congrats, and thanks for the help.

If the arm is a disaster, and I like the TT81 (and two arm wide deck/dust cover), perhaps two new arms.

60 day return, so cost of postage back is the extent of risk at the moment.

thanks for sharing your experiences and advice

thanks for your help.

as far as anti-skating, I find it to be a vital component of alignment/imaging/successful involvement.

The UA-7082 arm is effective 282mm, 11-1/8", so the arc and skate is different than a true 12".

After verifying stylus tracking weight (1.25g now), I match the arm's toy anti-skate indicator to start, then listen, test records, use McIntosh MODE switch to move things side to side, walking back and forth as it is manual thus not the listening position. Then I have my Chase RLC-1 Remote Line Controller with it's Remote Balance from listening position to help refine anti-skate. It's worth the careful work.

Then, for imbalanced engineering of occasional LPs, I use the Chase for active balance adjustment from the listening position. I have found a slight balance adjustment can make a very large difference, things just 'open up', various players now located/heard, now that specific track becomes more involving.

I find this LP is a big help refining anti-aliasing listening. Have the CD, listen for imaging of the 3 players, then the LP. Note: they don't all 3 play on every track, gotta read the notes for each track.
