Im looking for a bit of advice please, regarding tonearm mounting distance.
Ive just bought a lovely plinth for my Garrard 401, and I want to mount my Fidelity Research 64fx arm on it. The plinth comes with a blank wooden arm board, ready to be cut.
Geoff/Oldius is kindly going to help me with the mounting distance, using his Feickert contraption.
The distance I want is 231.5, Spindle to Pivot, and Im sure Geoff can do that. (with me supervising, of course )
Now, this is the bit that confuses me.
That arm will then be fixed there. It cant be moved.
Fine, if I have a cartridge and headshell which allows some leeway in positioning the cartridge. I can adjust it to get the correct angles etc. For example, I have an IO in a Fidelity Research headshell. I have some leeway in the headshell as to where the IO sits.
But, I also have a Fidelity Research cartridge which is different. The cartridge is integral to the headshell. There is no further adjusting possible.
Im hoping/assuming that since the cartridge and arm are both Fidelity Research, then this will just fall into place once I get the hole cut in the correct place.
But say the cartridge doesn’t then “line up” with a protractor? What can I do?
Or, say in the future I wanted to use a different integral/one piece cartridge/headshell, and it was a slightly different length to the FR version. How do I adjust for this?
Any help would be much appreciated.
