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

you are absolutely right about proper alignment. I have the tools and experience, I will be especially careful and re-check the longer arm setup. Like construction, measure twice, cut once.

I just bought some modern tools, goodbye Shure Sea-Saw tracking force guage, hello digital scale,

hello clear plexi block with 2mm grid,

hello new alignment disc (asked sister-in-law to give it to me for Christmas). I like that it is the thickness of an LP. I don't need the strobe on the other side, but, a confirmation, and when I help others ...

Now I use a 1/8" thick mirror for front view as it 'doubles' any misalignment in the reflection, perhaps I will glue a thin mirror foil onto the alignment disc somewhere.

The older you get, the harder it is to put a shim in one side if needed, and tighten those 2 screws.


JVC factory sheet shows the original was never straight

looking closely at your new example, it is not perfectly straight

Not sure what do you mean, but i’m talking about straight line of the tube inside the counterweight behind the arm tower. LOOK HERE on the NOS sample. Now look at your sample (do you think it’s normal?). The seller screwed the counterweight to the armtower with no gap in between, in reality is will never be so close when you will balance your cartridge with the right tracking force (depends on the cart weight with headshell, especially MC). When you will move the counterweight away from the arm tower then it will almost fell off. I know what i’m talking about, i had at least 4 different samples of this tonearm on hands. It depends on the condition of the rubber, but when the arm was NEW it was absolutely in line with the armtube, no matter what you can find online, i had a NOS unused sample sealed in the box (not only various used samples). People who think it’s normal may never had more than one sample (i had 3 perfect sample and 1 bad).

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.

Most are aware of your preferences but since Elliott had already 
purchased his table and arm, some of your words
were a definite "buzz kill".

Have yourself a merry Christmas.

this cheapo 100watt 100 v converter appeals to me as it adds no box or cords anywhere, just plug in.

I suppose I could use a cord to locate the little 100 watt transformer away from other stuff, which would be similar to using one of these, 200watt version

Any hum issues?

Any issue having the little transformer directly into a duplex wall outlet (that also powers 120v stuff via extension cord from the 2nd outlet)?
