If you are looking for a answer to your question you probably came to the wrong forum. Some engineers way back in time came up with the two null point system and the various percentage of distortion from there. There seems to be 2 to 3 popular null point systems. So if you go by there methods you have 2 null point with everything is supposedly perfect and the rest goes into various degrees of distortion. Love to meet the guy ,without seeing the record, who could pin point the null points with his ears. Now you are talking 10mm which is a pretty good distance. If you have reasonable math/ engineering skills you can go to vinyl engine and use there calculator to see if you can get 2 null points and where they would be using the 240 and 250 mm mounting distance. Then maybe take a record that did cost 100.00 and try it at 240 mm. I do not know how involved you wanted to get but thought I would give you the option to be able to understand a little bit of what is going on. There are guys on other forums who will do the math for you or run the calculators for you. Enjoy the ride Tom |
If the slots in your head shell, presuming you are using a head shell, are long enough you could possibly make up the deficit by moving the cartridge forward in the head shell and twisting it slightly with respect to the long axis of the headshell. Then you might achieve only a small tracking angle error, rather than a large one. Use a good protractor if you go this route. While I respect the opinions of the other knowledgeable persons who commented here, I personally do not think there would be such a dramatic reduction in sound quality, if you were able to make up for the pivot to spindle distance in the manner that I described. |
Well, this collection of answers gives me a good grounding. And a minimum of snotty gay comments like I get in other forums. Thank you all. I could as well mount the arm off the original 'table but I think that there's something to having a strict connection from platter to tonearm. But there's certainly a hierarchy of considerations. Over and out. Thanks. |
