Hi Brad,

That appears to be a different unit than the one linked. I must say it would suit my situation better. Do you have a link?

There are several models running from the cheapest that I listed for around $65 to over $400. They go from 200x to 500X mag that I've seen. What I'd like to know also is about the software and is there anything one could do to set up a "grid" so could roughly measure angles?

Hey guys,

This is the one I purchased. I bought this cheaper model just to see how it would work.

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=120556832599&ssPageName=STRK:MEAFB:IT

This is the one that Fremer used

Here are some videos of how the dinolite can be used.

Here are some pics of the measurement software in use by Wally
http://db.audioasylum.com/cgi/m.mpl?forum=vinyl&n=829896&highlight

This is where Fremer or Wally Malewicz who brought this to Fremer's attention came up with that ideal # to set SRA at.

Note in the pic of the cheap one I used that the plastic piece needs to be removed to get close enough to the stylus. The cheap eBay one did come with measurement software but I have yet to get the feel for using it that would prove to be accurate. One degree of angle is very minute in measurement and is hard to achieve with the cheap models software. Software does not include any gridlines. I have not experience it yet but I would think the Dinolite probably uses better software. Another advantage of the dinolite software opposed to the ebay model is it looks like the dinolite takes pics that are viewable full screen which the cheap model does not.

The tedius task is setting up to get consistant pics. The smallest movement can throw the view way off at this magnification. I tried numerous frustrating ideas before dicovering this magnetic base from harbor freight. This stand makes for stable and consistant repeatable setup. A dinolite holster was also used.

Notice in the pic that for this stand to work you will need room on your rack to place the base, not all users will have the room and other options would need to figured. The magnetic base was lacking one rod that I robbed from a soldering extra hands thing.

Almost forgot that lighting was another key issue, the light on the usb scope was not used. I opted for a usb led light for the backlight. This also proves to be very tedius to get just right to see the plain of the record to base your angle of the stylus.

You can set this up pretty cheap the route I took but will probably get a dinolite down the road just to see if the software would be worthy.

Many thanks for your kind comments! I must admit, my circulation numbers have been successful beyond my wildest dreams. My greatest challenges are to keep up the momentum, and turn all those eye balls into advertising revenue so that I can keep paying the bills!

I read the article by M. Fremer and consumed much of what he wrote. But, isn't there always a "but" I don't get the difference between VTA and SRA. If I have this right the VTA is the scribed between the plane of the LP and the center of the stylus shaft. So it is usually high, near but not 90 degrees.

Where I got lost was in the description of SRA, I had an idea that it was the complimentary angle between the stylus shaft and 90 degrees. But he said that is not what it is.

Any help would be appreciated. Not that I can change VTA/SRA on the fly, I just want to understand the delineation between the two.

Thanks,

Grainger
