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!

Hi Tablejockey, I’m waiting on response from OL. However, looking closely at my table, I don’t think the OL arm is going to fit, unless the frame that holds the arm tube rest is smaller than it looks in photos, or is up high enough to clear the platter. The RP10 plinth is narrow and only a couple of inches from the platter. Could be some contact when the arm is moved to playing position, and even more so by mid LP. Will update here when I have OL’s response.

 

Oh, Good Grief... I bet the part that would cause interference doesn't move with the tonearm!  I bet that's a fixed position part, and if so, the tonearm should fit.

Just completed the purchase, As this thread may be of interest to someone in the future, I'll post my thoughts and experience following receipt and mounting of the tonearm.  My thanks to those that contributed to this conversation.  

 

Received the tonearm earlier this week. Working on the mount to the RP10 plinth now. Things I’ve learned so far: The RP10’s top brace is magnesium, while the new P10 uses ceramic. Whatever Rega says about stiffness may be correct, but I expect it was the tarnishing of the top brace that led them to change to ceramic. It took a while to clean that up and get a nice polish. Rega’s 3 point mount serves an important purpose, in that it keeps the tonearm mount fixed in one place. Origin Live’s tonearm doesn’t have this mounting feature. It just slips through the mounting hole and has a washer and large nut below, but there is nothing to keep the base of the arm from moving. This presents a problem because the tonearm cabling is thicker, bulkier, and less flexible than Rega’s and it’s too big and stiff to fit in Rega’s cable clamp beneath the plinth. Therefore, when the cables move so does the arm base. I need to find a way to keep the tonearm cables from moving, perhaps use a cable clamp on the component stand.

The legs on the Rega plinth are not long enough to allow an easy bend in the tonearm cables as they exit the bottom of the plinth. I didn’t anticipate the leg length problem, but that should be fairly easy to resolve. The dust cover on Rega’s extended plinth surround is a few inches too short and will not clear the new tonearm, but that I did anticipate and expect to order a taller aftermarket dustcover. I’ve been wanting to display the skeletal structure anyway, but it would have been nice to put it off a bit longer.  

More later.
