Glad to hear you're back in the groove todd,
All the best to you

I agree with Mossy here. A bad batch to me has always been defined as imperfections with the disc & coating, not necessarily the lacquer compound itself. If the chip doesn't pick up, you make some adjustments to the suction strength or the tube etc… Discs that are bent, have bubbles, aluminum specks...

Tip 1!

If you end up making a "vinyl version" that is different from the digital master that the artist approved, be sure to get the artists/clients approval on it before sending it in to be cut.

Excellent!

Have you checked the fuse on the NG66H1 card (far left)

Groove echo also occurs in plating.

Best wishes to Kevin, Marci and everybody at Bill Smith.

And as an added Bonus!….

"This Neumann VMS-70 with Technics SP-02 motor is being offered with NO cutting head or amps."

Here's my experience with painting. I removed the front panel, gave it a light sanding in about a 7 inch area to expose the original paint color. Then took the panel to the local home improvement store and had them computer color match that 7 inch area. I sanded and used auto body filler in the ding...

You can check the hex bold on the pully of the fast motor. it could be loose.

Depending on it's condition, you might be able to flip that belt inside out too.

Great to hear

Does anybody know if polishing the mothers/removing horns affects high end?
I have no idea

JJG

You're so right, it's a valid observation in frequency reponse between the three graphs. I guess there are a few angles to the question. The Graph relates specifically to diameter loss and highlights a difference from Lacquer to mother to pressing. It's pretty interesting how the response in the gra...

No no that diagram was really cool!
Thanks James!

Thanks for the post The above diagram shows diameter loss, not loss from lacquer to pressed vinyl. Maybe some others can chime in, but I believe exposure to high temperature has a significant effect on high frequency loss. (as well as groove echo) i.e. after a lacquer master is cut & shipped, it oft...

It's really is pretty amazing
The science is all there, it just takes continued study to have it sink in.

I would imaging the sand would be all scrambled with actual music.
In the same way a single sine wav differs from a complex wave form on an oscilloscope.

I love it!

Hi Phax,

Did you get this one resolved?

JJG

I looked at the first 10 on the list….. none of which have lathes or advertise any kind of vinyl services.
