Yamaha YP-B4 Overhang 48mm?

Records & Coffee
Hello,

I decided to finally print a Baerwald protractor and set up my Yamaha YP-B4 with ADC QLM 36 MK III cartridge properly (in the past I just used the Technics 52mm gauge).

I found a number online (a thread here) that shows the correct overhang distance to be 48mm. (I do not have the original headshell or turntable manual). The Vinyl Engine does not have a manual for this turntable either.

My question is this: In order to even get close to the 48mm measurement, I need to bring the cartridge as far back as possible, which looks very strange.

Does this sound like something is off? Does anyone have a manual that states the actual overhang distance?

There was a number in the brochure that stated "overhang 10mm (3/8")". This doesn't make sense to me.

Any help would be appreciated. Thanks! :music:

Do you mean YP-D4? In the service manual for the YP-D4 the overhang is 16 MM. The effective length is 215 MM or 8 1/2 inches. Hope this helps.
 
Overhang is the distance the stylus hangs past the spindle, measured in a line toward the pivot point. For that measurement 10 mm makes sense. 48 or 52 mm, depending on which turntable, is a shortcut distance measured to the headshell connection but is not "overhang".

The arm cannot travel as far as the spindle, so there is no way to measure that 10mm length.

This is what the original headshell (which I no longer have) looks like:

You can see the indentation on the side. I believe that was the Yamaha mark for locating the cartridge.

If anyone happens to have one of these headshells, can you give the measurement from the o-ring to the center of the marking?

Thanks so much! :music:

I have the Yamaha YP-B2 which is almost the same TT. I've tried many different ways to align the cartridge. I used the mark on the side of the head shell for a long time. Which is the factory setting. I found the Stevenson alignment to be far superior. Than any other alignment there is for my TT. You can download and print it from Vinylengine.com. You have to sign up to be able to download it. LINK http://www.vinylengine.com/cartridge-alignment-protractors.shtml
 
Best way is to use a proper alignment tool then you don't even need to worry about the overhang because if the overhang is wrong, the ark will be wrong and you won't get the same alignment in both locations.
 
I now have tried with the Baerwald protractor, followed by the Stevenson protractor. It does seem to look OK with the Baerwald, and even better with the Stevenson.

It seems that the 48mm dimension must be the right number, especially based on that marking on the original headshell.

When I originally started looking at the alignment of the cartridge that I had set using the Technics gauge with the protractor, it was off by quite a bit!

Hopefully this thread will be helpful down the road to anyone with a Yamaha YP-B4 turntable, especially since very little info is available online.
 
I don't know what alignment Yamaha used, but the alignment that Technics used for their turntables when using the 52mm headshell length was Stevenson, using different dimensions (allowing for albums with shorter inner runout grooves, moving the inner null point closer to the label) than usually used. I've gotten very good results using the 52mm "shortcut" alignment on my Technics SL-1700Mk2, and no longer listen to anyone that insists that I should be using a protractor.

I just went to my Technics SL-1900 that I had used the 52mm shortcut tool on and put the Baerwald protractor on it and it looked perfect.

That tool really does work for Technics very well.

Thank you! That is exactly what I was looking for.

The interesting thing is that I need to pull the cartridge all the way back in order to get close to that dimension (and still I can't quite get there).
 
There are lots of Shure M 91 cartridge kicking around.

It would be a good cartridge for the Yamaha turn table. :music:
