Glad you are starting to get things situated. I am currently using a Conqueror Mk4 and an Enterprise Mk4 and my dual arm Origin Live Sovereign TT. In the past I have also owned the OL Silver Mk2, OL Encounter Mk3c, OL Illustrious Mk3c so have a little experience with your situation. The “finger tight” requires some pretty strong fingers, but know that you should not ever need to employ any wrench. It must be just tight enough that no rotation of the tonearm base is possible during general use. My normal procedure to accomplish this is to get the nut very tight by hand with the tone arm rest slightly to the right from the final position I wish it to occupy. Tighten the nut as much as possible under the table and then hold the nut and slightly rotate the tonearm base above clockwise ultimately placing the arm rest into its desired position. Rotating the base above while holding the nut gives one a little more firmness. These are very small adjustments. Snug it just enough until the arm does not rotate while you are setting the other adjustments or when in use.
Will Origin Live Conqueror tonearm fit my Rega RP10's skeletal plinth?
I'm considering replacing the RB-2000 tonearm on my Rega RP10 (circa 2014 - 2016) with an Origin Live (OL) model, probably the Conqueror MK4, and all indications are the hole diameter for the 3-point mount should be identical, but I am concerned that my RP10's skeletal plinth may be too small near the base of the tonearm for the OL's oval or triangular "plate" or "frame" that appears in photos above and around the mount base (where the Rega arm has its bias force adjuster.) If anyone on Audiogon has the Conqueror tonearm, could you take measurements of that part and respond? Additionally, if you have the Rega RP10 table and have replaced the RB-2000 with an Origin Live arm, could you provide your experiences? I'd appreciate it! Mounting should not be a problem if the base is small enough to fit the plinth. The weight differences between the Rega and OL arms are within a pound or so and I expect the plinth can handle that.
Thanks!
