What tracking weight do you use for rebuilt mmc2?

26 replies

Hi Guys,

What tracking weight are you using for an Axel rebuilt mmc2? its recommended to set it to 1.2g but it sounds much better at 1.7 to my ears. if I set it to 1.2g I seem to get distortion on really loud passages...

Any advice?

Thanks in advance,

Lee

 

Agree - they need a little more than the originals - mine was at about 1.5g. Best to adjust by ear.

No experience with these rebuilt MMC2s, yet (knock on wood that it's a while before I need a rebuild) but Peter is right on the money. Adjust by ear, no matter what the spec sheet says, if you're getting distortion, and upping the tracking a bit makes it go away, up the tracking force! Mistracking will definitely damage records, and quickly too!

Also, verify the actual tracking weight with a gauge, not just by the mark on the turntable. It could be off.

Also a good idea, I don't really trust the little adjustment gauge on the B&O tonearm as much as I do a more traditional table/arm combo. Not that you should really trust any of them.

I second these suggestions.  One of my tonearms is adjusted to what says is nearly 3g (it is an old TT) but the actual weight on the needle is 2.0g on a digital (calibrated) jewellers/stylus balance.  I've checked the cartridge/stylus today using a test record for mistracking and it's absiolutely perfect.

How do you test/setup tracking force on a tangential B&O turntable to check if the slider gauge is correct?

Thanks

It depends on the type of tangential Beogram.  On the BG8002 I have used a Shure gauge

Yes, I have an 8002.

What's the procedure with the Shure?

My 8002 was recently overhauled and restored and I am yet to fire it up.

I got a brand new SMMC3 and was going to set force at 1.2g. How will I know if 1.2g isn't enough? What are the obvious symptoms of not enough tracking force? I've got some mint brand new vinyl and a bit apprehensive about playing them without checking if my tracking force is perfect. Id say it would all be ok, but better to check I think.

Do you think that at 1.2g it will damage my mint vinyl or worst case is just it won't sound as good if the factory tracking scale is out of spec?

Thanks
