The U67 clone kit is available from Chunger's store now: store.studio939.com/product/ioaudio-mk67-bare-bones-kitBuild Thread: groupdiy.com/index.php?topic=57797.0Pricing has gone up a good bit compared to previous offerings: $425 for the PCB, board level components, and transformer. You'll still need: Power Supply: $60 Mic Body: $148 Tube: $50? Capsule: $250 (Heiserman) - $550 (neumann/senn) So total will be ~$950 - $1250 I'm sure I'll build one of these sooner or later, but the cost is scaring me off a bit for now, although I'm sure it's worth every penny. |

I'm actually shocked it's this cheap. .. I was expecting it to be closer to the mku47.

I'm actually shocked it's this cheap. .. I was expecting it to be closer to the mku47. Maybe I'm missing something.... but the equivalent u47 kit is $300: store.studio939.com/product/ioaudio-mk47-bare-bones-kitI think the total build for the u47 is more because you need two tubes, and I think a lot of people were doing more expensive bodies and capsules. Anyway, my reference point is really the C12 clone, which I believe had less parties involved, so it makes sense that there would be less total markup. Whatever the case, I'm enormously grateful for the efforts of the guys who put so much work into these designs, and sourcing parts, etc. Can't wait to hear clips, and eventually build one myself (as well as the u47). |

The MK47 is cheaper. The MKU47 is the more expensive one with the authentic looking body/headbasket, etc. I think. |

I was just looking at this last night..... I think I may do the 47... maybe the FET 47, that's a killer deal.

This is definitely not the same, the Chung is a Max of Ioaudio, and the one you posted is Danny of poctop/vintagemicrophone. Both guys are great at what they do, i have mics by both. |

Thanks for the links --- so you could do a DU67 PCB ($55) with AMI transformer ($110) and mouser BOM ($48), and be somewhere around $215 before tube, capsule, power supply. My guess would be that the IOaudio version would result in a closer replica, but it's nice to know there's some options. This is what poctop said on GDIY regarding the AMI vs BV12 transformers: "I would say that the U67 sounds awsome with both traffo , to me the U67 sounds like the in between the U47 and the U87 sounds but with the Tube sounds as a creamer. i would say that IOaudio Transfo is more on the U47 side and the AMI on the 87 side both i really love both" |

Yeah, I forgot to put that, but just putting up another option. Not sure if it's cheaper because you have to source from so many places. But, it does look like a very nice build.

Right on --- I didn't mean to diminish the authenticity or quality of dany's board. I was really just thinking about the ioaudio transformers that come with the more expensive chunger kit vs doing the budget build with an ami transformer. I understand max's bv12 to be extremely close replicas to the original. Although I believe max stills sells them separately and they fit one of dany's boards, so that would be another option. |

BTW, I recently heard that Shannon Rhoades of Mic Rehab was doing some capsule tweaking for one of Dany's DU-67 mics owned/built by Dan Deurloo, and Shannon was very impressed with the sonic quality and design integrity of Dany's clone kit... |

Here you go -- this is from the Gdiy thread:
"Confirmed, I emailed Sennheiser USA:
Yes we do still stock those capsuls as part #053225 for $553.38 each. Please call our sales dep. at 860-434-9190 x1 to order one."

I'm currently knee deep in the build, and just thought I'd chime in a bit. I do enjoy the style and design sensibility that Max puts into his kits. It is also nice to see someone who obviously designs in 3D from the outset. The kit is one of the most precisely-fitting ones that I've encountered! It also involves a relatively high number of tricky solder joints, but I think I've found some really sensible methods and solutions (suitable for people with only 2 arms  ). I'm taking my time on the build and thinking the steps through carefully. A couple of surprises for me were: 1) pricing higher than I expected, but we are still looking at a project cost just north of $1000 which is pretty typical of a high quality DIY tube mic project. 2) use of the OEM PSU pcb. I do not claim deep knowledge to make a judgement one way or another on this, but it does do a lot to keep the overall project cost down, and I am sure Max thoroughly tests his stuff and found the configuration optimal. My job is to just present it as prescribed, and I am anxious to hear it. As for general circuit implementation and BOM, there is not much that is different from Dany's offerings. If you were to point to one key technically defendable improvement, it would be that the HiZ section is quite a bit better isolated in Max's kit, and the component placement closer to original rendering a potentially closer match to vintage based on PCB topology. . . but sloppy build practices and wire choices could render those hiZ improvements mute, so I am making every effort to build it carefully and maintain all of the designed improvements in the final build. This kit should not be compared from a cost perspective to Max's new MKU47 which features a completely premium body that he machines in his shop and a FLEA headbasket. In this configuration, MK67 kit still utilizes a budget type Chinese body which has had a few small improvements from the first generation of the same body, but no quantum leaps in quality like the MKU47. I believe he is developing a kit to fit in the TLM67 for folks with deep pocketbooks and who want a really, really nice body.  |

Seriously though.... the more I read about the u67, the more I want. This kit looks peachy keen. |
