Heifetz' Tchaikovsky Violin Concerto Classic Rec

Thanks for your message.
Yes, I do clean all of my records with an Orbitrac 2 and the supplied fluid (alcohol base?) I also use Gruv-Glide before the first playing.
Many of my older orchestral recordings have similar distortion that I had attributed to wear... perhaps its my cartridge??? I do have a force gauge on order, so I should be able to verify the tracking force soon.
Thanks again,
Mika

After some fiddling with my TT, the distortion is noticeably reduced. However, there is a steady hiss throughout the entire recording. Is this tape hiss inherent to the recording, or is this record surface noise?

For what it's worth, I'm a big fan of Michael Rabin's performance. Rabin has a very different interpretation - far more romantic and less harried.
