Shelter and Triplanar matching ?

Tenmus,

I wonder how the azimuth adjustment (or anything else) was damaged on a new arm? I assume repairs will be covered by warranty.

Having to use the VTA tower near the top of its range "might" make it less stable and (let's face reality) the fit of the TriPlanar's VTA mechanism is not its best feature! Any chance of getting a taller armboard?

Since you had the same problem with this cartridge on another arm it does seem likely that the problem is in the cartridge. Shelter's QC is not as good as some, although I've never heard of this particular problem. Many 901's have misaligned cantilevers and/or non-square motors. Mine suffers from both problems (lucky me!) which makes it impossible to achieve decent channel seperation regardless of alignment or azimuth adjustment.

HI doug

I' am wondering too !!!! ( for the damage)

Thank you for the precisions concerning the Shelter .

I'll modifie the armboard to get it higher . However , now that I am using the REGA again with no special problems of height, I confirm that the problem I described you in my first message is still audible (piano with vibrato!!) and the headshell is lightly but clearly shaking lateraly ,especially at the beginning of each side whatever the anti -skate is.

I 'll give you some news as soon as I know what will happen with the TP ( because I want absolutly a new one THIS TIME).

Thanks again, André.

PS : excuse me but I don't understand what the abbreviation QC means (I am French).

Piano with vibrato - ouch!

That should not happen with a Shelter 901 on either of these arms.

1) Does this occur on only a few records? If so, are they drilled off-center? That will produce pitch-warbling every time. The only fix is to replace them or widen the spindle holes so you can center them before clamping.

2) If the records are drilled on-center it's probably the cartridge. Try another cartridge (any cartridge) and see if the problem repeats.

QC = Quality Control: methods used to ensure that every manufactured item or business process meets specifications, within defined tolerance limits. (I don't know the equivalent term in French, but it explains why one Exocet will hit the right house while ten Scuds can't even hit the right city!)

I had not this problem with my AUDIO NOTE IQ 3 before using the shelter .
Unfortunately I cannot try it again as I have lost the screws to set it up.

A friend will lend me a DL 103 so I can do the test...

OK for QC ( good explanation!!! )

It happens (very audible ) with piano records and not during the entire side ( but almost every time at the beginning of each side) . When the sound of the note is going on after the attack it seems there is like a vibrato ( tremulous) in the sound .

I have tried a lot of different records like EMI or RCA or else.They seem well drilled but I will check it .I effectively never had the problem with extra flat DECCAS 200 g reeditions.....but I have a lot of records and they are not all Deccas 200 g

Perhaps the problem comes from records but the fact is that I did'nt hear it with the AUDIO NOTE.

I hope that increasing the quality of he cartridge is not synonimus with leaving the half of my records on the shelves !!!!
