Brinkmann Bardo and Tri-Planar VII-U armrest issue

Just got a new Brinkmann Bardo. It was a snap to put the Tri-Planar am to the arm board drilled for this arm.

I measured the spindal to pivot distance of 233.5mm with my Feickert Protractor and set up the cartridge with the MintLP.

The issue I have is when I put down the arm, the arm will touch the arm rest and not fall at the beginning of the first track. By touching the arm rest, the arm is bump to several groove from the beginning of the track 1. I did try to fix this issue for the arm rest being too close to the platter by turning the armpod but without success if I want to keep the right S2P distance. Maybe I am doing something wrong. I would appreciate any comment/help.

Here is the fix/adjustment (there is nothing wrong with the arm)

remove the arm from the armboard

You will find a large screw in the middle of the base of the arm. Loosen it and sort out where the arm rest should be. Tighten the screw and reinstall the arm.

This will have a minor effect on the anti-skate, probably for the better.

Sheesh you guys! I ran into this problem years ago and realized that it was a setup problem (that article that Fremer wrote BTW is hogwash). Just do as I said- remove the arm (that is 3 screws) flip it over and you will see a single screw in the middle of the mounting flange. Loosen it, determine where the arm rest should be, tighten the screw, then remount the arm.

If you don't know what you are doing it might take 5 minutes. I can do this adjustment in about 2 minutes.

No other adjustment is needed. The Triplanar is the most adjustable arm in the world, but you have to understand that you do indeed have to set it up right to begin with. This screw is part of that setup; IOW if you have a problem with the arm rest being too close to the LP, you don't have it set up right and you have no-one to blame but yourself.

Tri is very aware of it- it is he that told me where to look in the first place. Funny its not in the manual though. I'll mention that next time we talk.

Hi Doug, I had a conversation with him about this yesterday. He maintains that when the arm is sent out, that the mount is installed according to a jig so that it is correct.

The problem is that quite often the arm board, which is supplied by the turntable manufacturer, is often not set up correctly (and we are not talking about this nonsense article that Fremer wrote- that is a topic for another thread). He explained that there are compatibility issues not unlike what you might run into between an amplifier and loudspeaker, but obviously mechanical rather than electronic. IOW some arm boards are simply drilled wrong and the problem gets blamed on the arm manufacturer. Tri thinks the blame ought to be 50/50...

However this solution works and he did say that they will be doing another owner's manual which will include more setup hints.
