JK, feel free to move this, i just thought it'd be good to post this here to get the attention of the non diy pro audio guys who may have been looking for an excuse to jump in? Looks like an amazingly easy diy and pretty great bang for the buck, samples sound nice, could be a great first project? R121 looking a bit?... store.diyrecordingequipment.com/rm-5-ribbon-microphone-kit/ |

Good thing the ribbon comes pre-tensioned. That's the hardest part and the most crucial to the sound.

a gentle reminder that if you are in a ribbon mood but not diy, i have a vinjet and 2 panther ribbons for sale all with transformer upgrades
But if you are in the diy mood, this kit was very well received and sold out quickly last year. This is a rock solid supplier: I'd say go for it looks like a fun build !!

i watched the time elapsed video construction of the mic, one of the worst build examples i've ever seen! The reason is because who ever did the build, had the ribbon motor with its uber fragile 1.8 micron ribbon sitting out in the line of fire for the entire construction? not only is that a horrible idea for obvious reasons, the magnets are super powerful and will attract any ferrous metal tool or screw to it, and rip through that feathery ribbon in the blink of an eye. just sayin |

The motor is only removed when it's about to have the transformer soldered to and placed in the mic body. |

tonycamphdDid you ever build this? Curious how close it is to an actual 121. Looks like one for sure.

tonycamphdDid you ever build this? Curious how close it is to an actual 121. Looks like one for sure. I can tell you a few things about the R121 compared to that picture. 1. The R121 ribbon is about 2x the width of that ribbon (those are the same long ribbon motor dimensions in pretty much every chinese long ribbon mic in the picture). 2. The R121 magnet carrier is machined, not stamped, and the little ears of the R121 are part of that carrier sticking out of the sides. 3. The magnets of the R121 are much larger than those on the motor in the picture, making it much more sensitive and higher output. 4. The R121 has "covers" over the ribbon gap which are made from a loose knit silk. 5. The gap between the ribbon and the magnets on the R121 is about that of a couple sheets of paper. The gap on the chinese ribbons is around 10x sheets of paper. This makes the R121 much more sensitive and changes the frequency response. 6. The R121 ribbon has about 3x the corrugations than the one in the picture. This makes it more sensitive and changes the frequency response. 7. The R121 is nickel over brass and doesn't ring at all when struck. The chinese one is clearly steel, and might need damping to keep from ringing. I don't remember what the transformer looked like, but I think it was a standard laminated type, not a toroid, in the R121. Anyway, it's not going to sound terribly close. My chinese mics, even through all their upgrades didn't sound like the Royer. They were perfectly usable, but still woofy and dark compared to the Royer. Different animals for sure, but for all the reasons mentioned above. I think if you were to change the ribbon on the chinese mic to something wider and more corrugated, and then add the silk and somehow get larger/stronger magnets, you could get much closer to the R121 sound. www.audiotechnology.com.au/wp/wp-content/uploads/2014/07/royer-ribbon-2.jpg |

Nope, I did a pair of apex 205's, then sent my less than stellar results to Samar, now the result is quite stellar IMO

...me too!...Mark's upgrades to the Cascade long-ribbon mic (1.8um foil, Samar toroidal tranny, custom acoustic plates, etc) make a major difference in the clarity, detail, response on both ends of the range, and overall resolution...a bargain!

www.diyribbonmic.com/This is the first ribbon mic I built of many. It's not as easy as the one above. Pre-cut solid brass body body. I had to build the motor, Cut, rib and tension the ribbon, form the grills, etc. I sure learned alot about ribbon mics. Listen to the sound samples. Sounds great.
