Hi Ben,

I should have read your first sentence more carefully. What you describe as vinyl is actually Victrolac, a "thermoplastic resin" that Victor developed for the long-playing Program Transcriptions. There was quite a bit of discussion a few weeks back about Victrolac on this list. 

Is the stylus picking up any dirt? Dennis Rooney described a problem with Victrolac records oozing sticky gook into the grooves. Perhaps he can respond and refresh our memories on this.

Hi Gary,

I never heard of Victrolac.
 I'm sure the record is clean, because I just cleaned it.
I cleaned it with "PURE 2 - Professional record cleaner from by "Nitty
Gritty"

I has the scroll label and it feels like vinyl.  Is it not vinyl?

Regards,
Ben
