Help all ye Triplanar Gurus

I received my Triplanar VII U2 from Singapore over the weekend and I may have screwed up big time while mounting the arm.Basically, the screw that adjusts the height of the cueing platform broke in the hole with the screw head coming off,with the result that if I use the cueing platform to lower the arm on the record it seems to descend from Mt. Everest. Manually lowering the Lyra Skala on the record is not good for my health.
Have sent a mail to Triplanar and also the Dealer(Audio Note, Singapore).
I doubt if any A'goners have experienced a similar situation but there is no harm in asking.You have to be particularly cretin like to have achieved what I have done.
Am also unable to align the cart using the Best tractor supplied by my friend Yip in Hong Kong coz the mounting holes on the wooden armband are a bit askew. This can and will be resolved.
Will appreciate any help/ advise to lift my deep depression.
Many thanks

Dear Thom, Just where in his post does Sunnyboy use the words "set" and "screw" consecutively? I do have to admit that as I re-read the post it does SOUND like he broke the set screw. I just want to be sure I'm not losing my marbles.

Lewm,

The "screw that adjusts the height of the cueing platform" threads into the back end of a square bracket sitting atop the silicone-filled cueing tower. It presses against the vertical rod that rises out of that tower and it is a set screw - just not the one you're thinking of.

No one referred to the VTA adjuster, nor does the VTA set screw press against a rod. It pulls the internal mechanism against the outer shell of the tower, quite different from what I described.

I know what you mean; I just didn't know what Sunnyboy meant. It should be much less expensive to repair the set screw than to repair the VTA adjustor (which is also a "screw"), so I hope you are correct. Anyway, we all agree he should go to Tri Mai with the problem.

No, you're not losing your marbles Lew. Like Doug, I knew the assembly he was referring to.

It's a tiny set screw, btw, using an .050" Allen wrench.

I suspect that this will have to be helicoil'd. I just checked the McMaster Carr website, and note that stainless helicoils are stocked down to a 2-56 thread size.

Looking at the standard range of set screws, it looks as if the screw in question is a 4-40 (one size larger than a 2-56). I say this because a 4-40 uses an .050 hex wrench.

So, the good news is that the parts exist to do the job.

Cheers,
Thom @ Galibier

Too bad Herb's up in hifi heaven. He could fix it in 10 minutes and yell at you while doing so. Or he would just replace the whole broken part of the tonearm using something he found on his workbench.
