Rega RP8 pladespilleren

[Music] this department here is makes the rp8 and the athlete in turntable models they're sort of mid-range and high in turntables and today we're going to have a look at the main stage is true of manufacturing and our Pietra turntable first process we have to do is assemble the outer frame of the rp8 we have to fit for acrylic strips that are custom-made for us into the end this is a purely cosmetic procedure but gives us the ability to provide customers with an outer frame and a lid holder the next process for us is to fit the the bottom brace this is one half of a stress beam assembly that gives the the light weight plinth great stability and strength [Music] these turntables have actually two sets of feet and inner foot and an outer foot as you'll see a little bit later on and the whole design of this is to make sure that we don't introduce any unwanted mass from the outer frame into the inner the shape of the turntable and we're pleased to say designed itself there's some critical dimensions on here 222 millimeters between the arm Center and the hub Center this is key for the size tone arm we use we know the position for these two components we know the position for the correct speed adjustment for the motor and then obviously the feet for stability and what that gives us is a turntable shaped if you cut around those key components and fits you're left with this quite unusual shape three inner feet are now fitted to the inside plinth simply screw it into place into the inserts that we've just fitted you ever have to see that simply locates into the middle of the outer feet meaning that the outside frame has no effect whatsoever on the actual performance of the turntable it's purely there to protect the town from dust you're looking at an RPA motor assembly here before it's fitted to the turntable obviously the assembly is made all in-house but we have the ability to adjust the phase of the motor and thus reducing vibration the little box you can see is a TT PSU which is a convenience that's an electronic speed change but its main function is of the a smooth power supply and the ability to adjust the vibration of the motor turntable now ready to go now it's time to fit the tone arm for this model it's the our Bao 8 uses Regas custom-made aluminium tone arm tube single piece construction very lightweight very rigid and perfectly designed for the this style of turntable Regas main philosophy with tone arm design it's very important to have zero play in the bearings a tone arm that can move this end obviously is going to add coloration to the actual playback of vinyl you want it to be perfectly mounted you want it to be Stern controlled when having extremely free movement as a production test we use a 20 milligram weight on-air tone arms that we allow that to tip and adjust the vertical bearings and the horizontal bearings showing just how free and the play and the movement of that tone arms are we just have a brief look at our moving coil assembly a painstaking process it takes a lot of patience and a lot of skill it's not something not everyone can do we're winding with a 0.018 millimetre wire it's incredibly fine that wire actually has two layers coating over it to protect it so the wire inside is even finer than that this is a job where human touch is key they have the control over the tension on the wire so fine they something that comes with a lot of practice and a lot of skill actually use his thumb over a little custom-made is nothing more than a glue bottle with a bit of foam and a pad in order to allow the pressure to be controlled during the winding the first job to do is actually to set up the wire lock it into position on the coil itself very small amount of sine immaculately easy to use just to seal the start point of the coil just to stop it unraveling during the wine the seams of wire this foil it's very difficult to identify which ones left in the right channel so we have to paint each tail with a color to identify at this point and winding begins so one set of coils is the left channel and then the whole assembly has to come out of the jig be rotated and we repeat the process to do the second Channel that's a finished cartridge without its coil so you have a hot very high-powered neodymium magnet coil assembly that you've just seen wound is fitted in Reverse through the back of the pivot pad and then the only adjustment we actually have is the position of this magnet its position to the moving coil itself so the build process has to be perfect all the way through this is the sub platter for the rpi tone arm we have a hardened steel spindle there hardened steel plate we use no ball bearing in this design the the spindle actually runs directly onto the hardened plate on the bottom there's both go off for hardening together at the same time so this material and this material or identical hardness so you get very little wear I don't think I've ever replace one of these and as we've been using this design for about 15 years 20 years I've never had to replace one through where you use High Point 80 motor gear oil one drop down the bottom two drops down the side to fit into place it would take a little while to settle because the tolerance is so tight inside as you can give it a spin that will help it go down but eventually that will sit flat [Music] you've got good eyes you'll be able to see this 3500 lines printed on here and we use an LED reading system reads the rotation speeds of about disk to two decimal places it's an extremely accurate the LED is lined up correctly making sure you can see and read the lines on the encoder disk runs around nine eight or nine revolutions takes an average reading over that time and hopefully in the second the box will show a green screen and a part but she does this is that the float glass platter for the RPI almost impossible to construct if you speak to most glass manufacturers you asking them to produce one Mars zero tolerance and three rings of glass and then stick it together invisibly for us it's a perfect material it's a flywheel effect platter so the mass and the larger ring is on the outside of the platter obviously that naturally wants to keep going once accelerated to keep speed stability and the turntable as close as you can get it to accurate [Music]
