Based on an old Helius model (Scorpio?) but much better made in Austria I believe. Highly rated since it was launched some years ago. |

They also used to be 'lively' arms - and I can say that as the Dual tonearms I use are very similar (as were the SME 'Improved' arms and Grace 707 which I really ought to sell. Possibly less well suited to plastic bodied cartridges as metal bodied types don't seem to 'energise' the arm as much. Now Andr'e - you want to get out of the HiFi shitfest? Just get one of these - or the Dual if they ever come up again - www.youtube.com/watch?v=nxtqsmgU15ADefinite proof as an aside that the AT91/Rega Carbon is NOT quite the same as a 3600L, as the latter tracks at 3g and the former at 2 and sounds horrid with all but collapsing stylus assembly at anywhere near 3g if mine is anything to go by... |

You having a laugh Dave. Bad enough having a Rega Toy but that is just the pits. Im already trying to hold on to the last bit of dignity i have left after buying the Rotel stuff.

'Course I'm having a laugh  I was tempted to try one of those 'Duals' though, as they seemed at least 'adequate' in engineering and might have surprised, who knows... That Rotel is fine, at least for elliptical tips and I'm pretty certain fine line types too, despite an error perhaps in overhang if the arm's identical to another model with different setting here. You spent a load of time (and money?) getting one immaculate model out of one pretty reasonable one plus a 'bitser?' The deck I really wanted from you once you'd moved on was that TD150 as I doubt I'd find another as good after your work on it. I was seriously in bits once I discovered you'd broken it down to sell off and probably chucked the rest... No way can I justify getting one until the other stuff here has gone (I need to bring down the TD160 in Super plinth to finish it off (I have a nice top plate for it), but I just haven't bonded with it the same as I do the 150. |

Always been the arm overhang with that ROTEL. it is suppose to be variant of the JELCO 'SA50' but even though its near enough identical visually the geometry is totally different. 11mm overhang is just wrong. How can you fit exactly the same arm of two different decks in the range yet have different overhang spec, its just wrong.
Sorry but the 'TD150' fetched far more in pieces than a whole. wtf you want one of those for is beyond me.

Same reason you did? Can't afford a TD125 now and I should never have let 'mine' slip through the net as I did..

The 'R200' landed from Johnny at AO. Real nice condition. Ill rewire it & fit a new Bias belt over the weekend. Bias belt feels like its not broken yet which makes life easier. LOL

Im surprised no one aint done a proper String/Weight bias modification for the arm yet.

Johnnie did once.
Proper, with thread and weight? You're having a laugh! The magnetic system is frictionless and for fifteen to twenty years of that tonearm's life, it's been utterly reliable.

LOL Thats why the best arms in the world use string & weights.

Whilst it’s not hard to grasp how a thread and weight works, I don’t know how the R200 or RB250 apply bias.

Best arms in the world using thread and weight bias correction running through a loop in a bit of wire? Some arms use a fine spring and lever affair hidden in an assembly often combined with the arm rest (many Jelco's for example) and these can be elegant and accurately calibrated. The Rega arms use opposing magnets so totally friction free. The R200 slides one cylindrical magnet up and down the pillar (the toothed belt actuates an outer plastic cylinder assembly to move said magnet) to react with a fixed one set at the top from memory which I think rotates with the cradle, making for an admittedly more complex arrangement than the one on the RB models which uses the pointer or end sleeve to slide one magnet back and forth. Set and forget  |

The Magnets in the '200' have also been reported to have lost their Magnetism in some cases. Some people believe that Magnetic cartridges these days dont need Bias control applied LOL
Once saw a picture of a guys R200 where he removed the lateral balance weight & fitted a rod for a string & weight Bias in its place. Did look quite good, cant seem to find the picture.
Shame about that Jelco arm being short & a nightmare cos its actually a better made & finished arm. If it were a proper 'SA50' or the 'SA200' i would have fitted that.

Hint - The R200 ALWAYS had bias levels set too low which is polar opposite to the RB types which are slightly too strong. The current sliding cylinder arrangement is 'do it by eye' more than anything wlse and I again have a very crude way of setting it which seems to work as styli subsequently wear evenly... varies with the stylus used anyway...
