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


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

I don't mean to start a good, better, best, 'here we go again' tech talk about 9/12, that has been covered, and I have been researching.

I am just wondering: Who tried and ended up preferring a 12" arm?

Aside from all other upgrades you probably did at the same time, which could have improved a 9" arm, what about the 12" arm made you stick with it?

I suppose, 'I tried 12" and went back to 9"' would be good to know also

thanks, Elliott

Ouch!
Sorry for the disappointing result.
Unfortunately all too common with UPS.
I swear they could break a rubber ball!
Good luck in your renewed search!
Time to throw out all my vinyl replay gear obviously then and grab myself an old ipod and set of earbuds.

I hate cricket...….
As I have said before Lewm, sometimes stuff works even when on paper it should not.
But the last time I made a statement along similar lines over what I tried and it sort of worked, Chakster jumped all over it.
Maybe he has mellowed and realized that sometimes it just works out.
I have to err on the side of Lewm regarding dustcovers.
I will be blunt and state I have no idea what causes the difference but playing with the dustcover in place and then with it off is akin to lifting a shroud on the music.
It sounds corny but it is more open and dynamic with dustcover off and this is from THREE separate tables.

I use the dustcovers for two reasons.
To keep dust off the tables when NOT in play.
To provide a nice resting place for my tired old cats who otherwise would sit on the darn platter I am sure! 
Not familiar with that Pioneer arm but you would get yet another huge Victor plinth and a lower model tt-61 table to boot.
Guess that depends on what f you need any of that or just resell minus the arm thereby getting the pioneer arm for cheap.
I can't imagine it is as good as a 7045 though.
Elliott
When I was looking I was lucky and stumbled across mine right here on Audiogon, it was the only complete all Victor dual arm plinth version I had seen at that time.
We struck what I thought was a fair deal but then like yourself I was shocked at just how large and massive the plinth was when I unboxed it and saw it in person!
Setup was a breeze and I already had a stepdown from my Victor TT-71 so was ready to play music right away.

I am sure you will be very happy with it indeed.
Merry Christmas and enjoy your present to yourself, the best kind!
Probably busy with, you know, Christmas stuff.
$912 USD sounds fair especially as it has the x-1 Cart and a step down transformer.
Hope it works out for you.
Amen!

And apologies to the OP for labouring this point.

Elliott, please do update on your decision if you go the way of the other all Victor combo or another direction entirely.
👍👍
Interesting pictures that do not quite tell the whole story as you are painting it Chak…….

If you look at a few more pictures on the net you will clearly see the one you posted has the whole collar askew.
There are quite a few with a straight collar and some degree of sag that is genuinely from the rubber but do not look as bad as the one picture you posted.

However you want to beat it to death, the terminology is NOT defective or broken!

Although the picture you did post would qualify as broken imho yes.
C'mon now Lewm.
Chakster is always right and has to have the last word......
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.

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!
Mijo.
Elliot bought a Victor TT-81 cw ua-7082 arm already......

Hence the last few posts have mostly centered around the attributes of the 7045 and 7082 arms.

I have no doubt the Poly Super 12 is a mighty fine table though.
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.

Reaction of the rubber to chemicals present in the environment and natural degrading of the rubber over time, these arms are 30 to 40 years old.
Once a counter weight is mounted then the laws of nature and gravity will take over and again if have been in use for 30 to 40 years.…..
One possible reason for some arms showing more droop than others could be the weight of the cartridge used, a heavier cart will mean the counterweight was mounted further back to balance the arm and vice versa.

All of these factors explain just why most of these arms show some droop to one degree or another and why the amount of droop may differ.

My 7045 has more droop than my 7082, could be any of the above including maybe it was a nos example not used for many years. Who knows unless you personally owned them from new.

Certainly we should NOT be describing these used examples as "defective" as some have done as they clearly are not so.

Now common sense rules and if you see a droop of 45 degrees or more then yes I would be concerned but a couple degrees from level?

Just my take on the arm situation.
That's a fair price for a UA-7045 arm and yes likely to show some sag on the rubber.
From my experience unless the arm has never been used then they are ALL going to have some small degree of sag in that area.
The 7045 on my 71 has slightly more sag than the 7082 on the 81 but I have not worried about it one single jot.
And unless you are an absolute perfectionist for every detail I would just dial it in when you get it and see what you think rather than worry about a slight amount of sag.

I was also considering setting up a second arm for mono but not sure yet if I want to or need to start off down that rabbit hole!

Good luck and again congratulations on your purchase of what I am sure you will come to agree is a fabulous vintage DD table!
Sounds like a job for Christmas Day after all presents opened and everyone is now bored.

Stay tuned,it’s a heavy beast to move in that plinth.
The 71 was out of the playing arena which is why I could check it easily 
Totem
i just examined my tt-71 and there is no voltage block for changing voltage input.
i would be very sure there is not on the tt-81 either but as I am playing albums on it right now not going to get checked for a while.

I am fairly sure that neither the tt81 or 71 have the input voltage change block.
A step down is likely required and cheap insurance.
The TT-81 is a 101 sans Double Bi-Directional Servo and with a simplified pitch control system/display ; the functions and features are nevertheless the same : +/- servo, ±6Hz of 440Hz without switching off quartz-lock switch, soft-touch transport keys and electronic braking with reverse-current circuit.
Not quite correct as it is the TT-71 that has the soft touch transport keys, the TT-81 has a more "normal" button for the transport keys.
I wish we could edit posts like other forums
??
Sure you can edit your post but you do only have a 30 minute window from initial posting to do so.
Mine was a dual outlet model so I could power both my tt-81 and tt71 from it.
it came with a built in cable of about five feet so cannot comment on the almost wallwart style of your first link.

I have mine removed in distance from both the TT and power strip and I hear no hum whatsoever.
OP.
Do not forget to purchase a 120 to 100 vac step down transformer or you will run the risk of a melt down.
They are plentiful and cheap on eBay.
Good luck and enjoy as I am really happy with mine.
Chakster
I do agree with the sentiments of cost of repair for the 101.
Part of the reason I went with a 81.
And a 71 but that’s another story.

However I feel a good working 101 is likely near the Pinnacle of vintage DD table charts and if money was no object or concern I think I would pursue one.

BTW, the plinth on the 81 of mine and the the one the OP has bought is massive and very solid weighing in at about 40lb on its own and is a multiple layer construction.
Will be hard to beat that plinth.
Elliot.
Congratulations!
I have the EXACT same setup and I can tell you there was also an optional lift off dust cover made specifically for that plinth.
I know this as mine came with it!
You may get lucky and find one or as you say, have one custom made, likely $175 or just over.

It is a fantastic combo and I have tried various vintage mm carts on it and all are a breeze to setup with the on the fly vta .

Don’t forget it’s 100vac so you WILL need a step down transformer for USA 120vac mains, again plenty on eBay.

That 7082 arm is the business for sure!
Have fun!

P.s. feel free to pm me if you have any questions on this setup.
