Cool video. Really shows what is going on. Lots of schmutz on the record also. |

Nice job on that brass weight! Shoot for 9-12hz resonance, lower is better than higher but the ears must provide the final judgement. Wild oscillations at the resonant freq are not good. Presumably splitting the difference to ~10hz would give moderate oscillations and hopefully more open sound. At least you will know that the arm/cart combo is happy. With a heavier arm, that weight would probably be perfect but you have to adjust for the conditions at hand. |

Thanks guys It took way too long to make that brass weight. Screws for cartridge had to be counter sunk with a flat bottom. Screw hole for arm mount had to be threaded.at m3.50. This I all way smaller than I am use to and my shop is set up for wood working not this small stuff. Need to listen more and tweak arm adjustments before I make a 2gr lighter mount, but I suspect that is where it will end up |
