Roller bearing guides' effect on the 'longivity' of the tapes............
« on: September 17, 2011, 08:40:34 AM »
I understand how it could improve the sonics.    Since there would be less 'scraping', would this imply that the durability of the sonic signature of the tape be 'significantly' improved  compared to fixed guides?

Btw.  How do you know it's my real name?  Just because I say so?

Yes. Take a look at the fixed guides after the tension arm rollers on a heavily used RS1500 and you will see flat spots on the fixed stainless bushings, where the moving tape has been rubbing and wearing it down. The bushing is also wearing the tape surface, burnishing it at the very least and likely it is removing some oxide with each pass.

Yes, my RS 1520 had that issue. One of the guide sleeves was almost worn through!
