I am presently using a BSR crystal cartridge with turnover stylus. I am not entirely happy with the quality of the sound and was wondering if anyone can recommend a cartridge stylus option to give better quality whilst still giving sufficient output to drive my sound card. The crystal cartridge gives an output of 700mV which is rather high and tends to over drive the soundcard. I am using a Goldring Lenco GL75 turntable and BSRSX6H cartridge and stylus. Any advice regarding CD copying with a PC would be appreciated, especially regarding cartridge/stylus. TIA. I don't know anything about the condition of your 78's, etc. However I'd suspect that a completely different cartridge, etc, might may a significant difference! I don't know what specific cartridges these days can be purchased with stylii/cantalever designed for '78' replay. However people like Shure used to do this. If so, I'd recommend buying a modern MM or MC cartridge with a suitable '78' stylus, and an RIAA preamp. (Although you may need to modify the output depending on the brand/date of the discs - particularly if you already do this to take into account non-RIAA recordings.)

Ian You could use something like this http://www.shure.com/phono/m78s.asp but it depends on if your arm and turntable is up to it. It depends on just how many and how importanat they are to you. You could use something like this http://www.rega.co.uk/html/planar78.htm I also don't know what sort of phono amp with what sort of equalisation would give the best results, but with a moving magnet as opposed to crystal cartridge, you will need some additional amplification before the sound card. -- Nick "Life has surface noise" - John Peel 1939-2004 |

Thanks for that. I am an electronics engineer and a radio ham so am happy building my own kit. I am working to a very tight budget at the moment as I have been off work ill for over a year so have to keep an eye on the pennies. Thanks again. Ian -- Ian Pollard//Wooler//Northumberland//UK |

I am presently using a BSR crystal cartridge with turnover stylus. I am not entirely happy with the quality of the sound and was wondering if anyone can recommend a cartridge stylus option to give better quality whilst still giving sufficient output to drive my sound card. As you probably know, crystal cartridges were the bottom of the barrell in the days of vinyl. Not only that, but they were frequently mounted in turntables of equal or worse quality. The crystal cartridge gives an output of 700mV which is rather high and tends to over drive the soundcard. I am using a Goldring Lenco GL75 turntable and BSRSX6H cartridge and stylus. Any advice regarding CD copying with a PC would be appreciated, especially regarding cartridge/stylus. TIA. Just about any decent cartridge will be magnetic and therefore require a preamp. Many options exist - these guys have an exhaustive list of options, some of which should also be availble in the UK: http://www.kabusa.com/frameset.htm?index.htm As far as cartridges go - its a matter of what your pocketbook and turntable will support. The Lenco GL75 looks like about one and-a-half cuts higher than the bottom of the barrel. You don't want to try any cartridge that is too sensitive or has too low of a tracking force in it. The Shure in particular looks like it might be robust enough for the arm. http://www.shure.com/phono/m78s.asp http://www.needledoctor.com/s.nl/sc....t.A/id.1057/.f Here's some good articles about transcribing LPs: http://www.a-reny.com/iexplorer/restauration.html http://www.delback.co.uk/lp-cdr.htm |

If you're using a cartridge direct into a soundcard, I'm not surprised you're 'not entirely happy'. A ceramic cartridge needs a very high impedance load (at least 1Meg) if it is going into an unequalised input. A simple op-amp unity gain buffer using a FET input amp (even a TL071 will do) should make things a lot better. -- Chris Morriss |

The Shure in particular looks like it might be robust enough for the arm. FWIW I used an M75ED, and then the V15/III for some years with a GL75. Although not ideal in some ways - e.g. LF resonance - the combination worked quite well, and the GL75 is very useful for old '78's that are actually some other speed like 80rmp, etc. Hence I'd say that the GL75 (in good condition!) and a decent Shure with a '78' stylus might be a good combination for this kind of thing.

I think you'd find difficulty in buying a ready made pre-amp for a ceramic cartridge these days. Not that I'm sure anyone would want to - although there was a time when it was thought they might be a way forward. The BBC once used them on one of their turntables - probably designed in the '50s. The cart was an ACOS - can't remember the model. Then there was the Decca Deram. -- *Why isn't there a special name for the back of your knee?

It actually had a real cantilever. d Pearce Consulting http://www.pearce.uk.com |
