So 1.25 inch = 31.7 mm Basically you could expand your mounting hole towards the platter by only 0.39 inch to mount another tonearm with 230mm (9.05 inch) Pivot to Spindle distance like Fidelity-Research FR-64fx. The top plate of the FR tonearm base will cover 53mm (2.08 inch) diameter above your plinth anyway. Look at FR-64fx in my system (in the middle of the picture gallery). |
Looks really solid, I was about to make a trade for a sp10 that had a fidelity research fx64 s on it but he backed out. I read that if the vtf was hard to turn it would need to be cleaned and regreased Did you have your cleaned and regressed? the plinth is corian several layers I’ll have to look into what to drill it with thanks |
I read that if the vtf was hard to turn it would need to be cleaned and regreased I did, but only on my 66fx and only because the side panel fell off on arrival. Look at the VTF spring of my 66fx with new grease. My NOS samples of the 64fx are all fine, two of them. I also have 64fx PRO and it’s also fine. As you might know the fx series was made in the '80s and overall quality of some parts are better than old 64s from the early '70s. The armlift and arm base are better on FX, dynamic tracking force is always in better condition that on 64s. So the problem you are talking about is a common problem for 64s , but not for FX series. |
I learned this from a guru, and it turned out to be correct. Sometimes the FR64S and probably the 66S, so maybe the 64fx, pivot can feel kind of "stiff" at first. This may also apply to the VTF adjustment. The guru advised to just put the tonearm under a heat lamp for a short while, to cure the problem(s). I did this with my 64S, which did come to me with a feeling of viscosity in the pivot and a very stiff VTF adjuster. The heat lamp cured the viscous feeling in the pivot bearing entirely, and the VTF adjuster got looser, but the latter is still a bit stiff. I think you want it that way, so the chosen setting does not vary during use of the tonearm. Despite the fact that I am using my 64S in my basement system, where the ambient temperature is typically in the mid to high 60s, cool by US home standards, the bearing has remained free after that one heat treatment. |
