Queen RP1 speed issues and RP6 upgrade questions

    I'm new here so forgive me if these are common issues. I have a few bundled questions to throw in.

    I have been running my queen rega RP1 for around 2 months (owned for 6 months but took my time completing my setup) and around 2 weeks ago I started having speed issues where the record would dramatically dip in pitch and then correct itself shortly afterwards. This continues to happen periodically and the dip is seemingly random and very annoying.

    My immediate reaction was to buy a white belt thinking the stock belt might have worn out but that didn't fix my problem. I can see a slight warble in the platter but I'm not sure if that issue is coming from the platter or the sub platter and Im a little lost at what to do as my turntable is not enjoyable any more :(

    Does anyone have any useful tips about where to go from here? I am pretty frustrated and ready to frisbee the thing out the window. I have a basic understanding of the turntable components and upgrades but I'm still a novice. I know groove tracer do good sub platter and platter upgrades but I'm not sure if its worth spending that kind of money on an RP1. Eventually I would like to upgrade to a planar 6 and considering the planar 6 comes stock with an upgraded sub platter I'm not sure if the GT sub platter purchase is future proof to a planar 6. Does anyone know how the GT reference sub platter compares to the Planar 6 sub platter?

    Is it worth chasing upgrades on an RP1 or should I upgrade the whole TT? opinions welcomed.

    Thank you to anyone who answers.

    My current setup includes:
    - Queen Rega RP1, ortofon 2m blue
    - NAD C350
    - Rotel RQ-9708x phono
    - Dali zensor 7's

    I have a completely upgraded RP1. If the P6 had been available at the time, I would have bought a P6. While my RP1 is incredible sounding, it is only worth about $450 even with all of the upgrades because it is still labeled an RP1. Hope that helps you to decide.

    It is possible that the pulley is loose on the motor shaft. If that is the case, you could re-glue it.

    The GT Reference subplatter is excellent but the one for the RP1 is not transferable to the P6. The GT Reference subplatter also has the sapphire thrust plate and zirconia ball bearing which results in an extremely low noise floor.

    I don't own a Rega but the issue you describe doesn't sound like anything that an upgrade would fix. If there is an intermittent dip in run speed, followed by correct speed, repeated, I would guess that the motor is the issue. I would contact the dealer ASAP, assuming you bought it new, and ask them to take it in for repair. I suppose I could even see a poorly lubricated spindle bearing becoming a speed issue, but I don't imagine that speed variance would result. I would wager you have a bad motor in that jobbie.

    I was also thinking perhaps the AC motor, or maybe the circuit that sends incoming voltage to the AC motor (my Music Hall MMF-2.2 uses a few capacitors).

    The Planar 6 is significantly better. Just about every part on it is higher quality. The only thing that is really similar is the dustcover. It's caraxy to waste money on parts for an RP1 when there are two tables with better parts withing the same price range of upgraded parts, and which will hold their value better as units; the Planar 2 and the Planar 3. If you can afford the Planar 6, I recommend that you take the RP1 back and get creidt for that towards the Planar 6. You'll have no regrets there. The issue you describe with the RP1 is most likely the pulley slipping on the motor shaft. That's an easy fix.

    Thanks for the feedback everyone, I hadn't considered that this might be a motor issue or even faulty at all. If thats the case then I cant even sell it :(

    I did get the table brand new but it was gifted to me for my birthday, I wouldn't have chosen the RP1 myself as I usually hold out and make purchases that have longevity. My whole family chipped in and now I have to have that awkward conversation where I tell them I need to return it.

    Cheers for the upgrade advice, I'll most likely try to get this table in working order and get rid of it.

    Just so you know, I contacted groovetracer about these. All rega tables are compatible with the GT subplatter, however the original RP6 glass platter is not compatible with GT sub platter. You can still use the GT subplatter on an RP6 but you must also couple it with a GT acrylic or delrin platter, I assume because of the recess. If you want to continue using the original RP6 glass platter then you have to buy the GT reference platter made specifially for the RP6 which I'm guessing has a longer spindle. Also note that the new Planar 6 is a completely different table to the RP6 and does not have the same issue.

    What I still don't know is how the GT sub platter compares to the new Planar 6's aluminium sub platter that comes stock. I would assume the GT sub is superior but so far I haven't found anyone who was able to make that comparison which probably means the stock planar 6 aluminium sub platter works well.

    Thanks again all, good advice all round.

    Listen to Bill (KT88), he has been selling Rega's for years. You most likely just have a slipping motor pulley. Touch of glue and you are good to go. The P6 doesn't need to upgrade the subplatter, the factory one is good enough.

    Is fixing the pulley something that is fairly easy to do? or is that a fix that would require professional servicing? I'm proficient with basic electronic skills and I'm confident beyond a regular person. I would like to avoid posting the unit back to where it came from if I could.

    Oh. I didn't know the pulleys were glued on. (my Music Hall table has a little flat screw on the aluminum pulley that's tightened with a jeweler's screwdriver)

    You do not need a professional to re-glue the pulley. Pull it straight up with your fingers, add a couple of drops of a decent glue, put the pulley back on, let the glue set up. Return the belt to its position and try a record to see if your problem is solved. I've owned a Rega table for about 13 or so years.

    Don’t worry about the awkwardness factor. Your family would want you to be happy with it. I’d return it and use the credit towards something slightly better, that’s if you’re serious about vinyl.

    I think you will get more satisfaction in the long run.

    Agree...higher model turntable is a much better plan than investing in upgrades to the RP1.

    I know by experience. I now have two RP6's in my two systems, and my heavily upgraded RP1 is packed away. I loved that RP1 and it served me well but really no comparison to the higher models.
