Guys,
I'm not promoting the scope or my RCM. I have no affiliation with either. I have owned my RCM for quite a few years and have been very happy with the results. Whether or not you own a RCM, wash your records in the sink, brush them, wet-brush, etc...or whatever ..... the only thing that is relevant is the final result.
This little scope has opened-up my eyes.
When I started this thread it was simply meant to show that even though we may think our records look clean after doing the cleaning ritual we are accustomed to, a closer look may surprise us.
I spent $69 to look at a bunch of styli I had in my collection. In the process, I saw what record grooves look like, both before and after cleaning.
Second example ..... a fingerprint on the record:
For this, I have taken a used record which sounds just fine. However, upon closer inspection I found a fingerprint. I took a pic with the scope (150x) magnification. For a marker and point of reference I have circled (yellow circle) two physical marks on the spot of the record next to the fingerprint (in red rectangle):
Washed and vacuumed the record on my RCM:
After the wash, I brought the record under the scope and looked at the same spot. Notice the same two physical marks on the record (in yellow circle) and notice the spot where the fingerprint was on before (in red rectangle).
The fingerprint is gone:
Still trying to get used to this little scope. It's not easy focusing on something that's been magnified 150x.
However, I am really glad to share my experience with it and show my fellow members what I see when I look really really close.
Cheers.
