USA Cueing Device Drops Fast

The Jelco cue assembly is universally employed in many high end manufacture's tonearm, therefore, Jelco cue failures would not be limited to just VPI. I can't speak to Jelco or the VPI produced cue failures as my cue assemblies continue to works without issues.

Just curious , how old is your tt? I'm on my second arm. Came downstairs tonight for some vinyl listening and spent a few minutes "loosening up " the cue assembly becaause it would not drop all the way down. It would just hover over the record. Once it drops I have enough clearance so it has nothing to do with the height of the cueing assembly. I may experiment with leaving the assembly in the down position and then remembering to lift it up before I play my first record

My most current VPI table is just over a year old. I've owned aver 8 vpi arms and none had cue problems.

My short investigation showed that users of other turntables with hydraulic tonearm cueing systems, which is almost all of them, have the same complaints as the folks here. Still, none of the hydraulic cueing devices seem overly complicated, and it would seem to me that they should be more reliable. Does anyone know the reasons for the failures. I would assume that the main causes are small leaks and a lack of uniformity in the damping fluid, or fluid of the wrong viscosity, which should be correctable. Aftermarket damping fluids having different viscosity is sold on the internet. Rich

I think part of it is since the system is 100% sealed, the silicone fluid dries up or thickens over time. I've rebuilt the Jelco and Clearaudio lifters with new fluid, a cleaning and a little bit of patience and they have always returned to work like new. I think the current designs just require some maintenance every few years but nobody wants to come out and say it.

Maybe Carlo from Tru-Lift/Integrity HighFi can reinvent the wheel for VPI since he did such a nice job on the Tru-Lift.

It was getting rough using our previous arm-lifters because when we received they were either 100% or dead on arrival and getting them swapped/replaced was a no go. Some shipments nailed it others would be 50% unusable. We have been working on ours and there was a bit of a learning curve with our initial batch were it came down a bit too fast/real time, but we have stepped it up and are finding that they are working without a problem now. We had actually planned on waiting longer on our arm lifter but last year during the holidays we got hit with a shipment from our former supplier that was almost all unusable and it killed us on getting tables out so we had to push ahead of schedule on our own. Should be good all around now, also those having a problem we found that it is when the set-screw on the side is just a bit too tight.

Ok Mat , thanks for the response. I will try to loosen the side set screw tonight but it seems that there is not much of a "window" between too tight and too loose where the whole cueing mechanism drops.

Just curious, what does the side set screw against a solid metal cylinder have to do with how quickly it drops ( in my case i have the opposite problem )?

It can potentially apply just a touch too much pressure on the piston inside mechanism which is fouling it up. It took us a bit to discover this because the intense testing (flipping it up and down) happens before we we mount it in the base. This was what he had always done to test the arm lifter with the previous supplier as well and was the fastest way to see if it was DOA or in good shape. After that/mounted to the base my guys put a weight on top of the arm to represent a cartridge and test it some more. Most of the lifters with issues have been resolved with backing off the set screw :)

Hi Mat, OP here. I tried backing off the set screw, but I'm still having issues. The cue mechanism drops at the speed of the lever so I'm forced to manually lower slowly.

Let's address the elephant in the room. What is VPI response to owners with a defective cue? Will a replacement be provided and what conditions must be satisfied? Does one go through their Dealer, or work with VPI directly? Do I need to return my defective cue before a replacement will be provided?
