Curious, as you have 115-120 v in the wall, would the psu just run the actual voltage as it doesn’t see 220v ? If the supply was a high frequency self switching supply but ours is not. it 120-0-120 toroid that runs the primary in series or parallel depending on the switch. that means that if you have it switched to 230v whilst using it in the USA, it will only see half the needed voltage. your tube will starve. thanks. ben Thank you, Ben. Any thoughts about my noise issue? |

I listened to the clips I recorded with Jim's BU67. While there is a gain difference, I did not hear this noise issue on Jim's when comparing it with my MK67.

Do yourself an enormous favor and get an old 1960 Telefunken EF806s (small s, that is critical) - Made my Neumann U67RI sound like the vintage units I have loved. The difference over a regular EF86 is astounding, if you want that sound. And as just mentioned above, the Amperex EF86 from the late 60s (mine are from 1967) are just superb for finished glassy tone, like an M269 Actually that comparison on how the Amperex sounds is really accurate. There is a more forward tone in the mids that definitely gets that M269 vibe with my MK U67. |

Thanks man, I try my best to be accurate! LOL I tried a Tele EF86 Silver in mine first, but settled on the Amperex. Tele was deeper in the low end, but much more open on top. Amperex was more mellow on top with a forward mid push that I really liked. It's worked on a lot of voices too. My wife's voice is basically done and doesn't need or want any EQ. My friend Ellen has kind of a Celine Dion style voice, and that mic sounded great on her. My brother has a Sam Smith kind of R&B voice and it just worked fantastically. Anything lighter in my voice; rock, pop, etc, it works great. |

The more I play around with the BU67, the more I like it. This one has an EF86, so I played around with swapping the tube. I like what the Amperex Tube does to the mid range, but it also looses some low end. The BU67 is a slightly different beast than my MK67. Whether it’s Neumann K67 Capsule, which we have all discussed can be brighter than the vintage capsules, or just a combination of things, the MK67 is more open. I even tried swapping in what I assume is the Mullard EF86 from the BU67 into my MK67. That gave it a touch more low end and less midrange push. I think with the same tube they were both closer. I may have to pick one of these up. Need to try it on Emily first. That’s the final test. mics which EF86 were you using in the EF86 version of the mics? Can I order one in this configuration? Here are some quick clips I did last night acapella of me swapping the tubes between them. I even threw up my FleA 49 for good measure. Clips are not level matched. www.dropbox.com/sh/oc5skx1nb944q4y/AAAG2BXHLWZGA7GgzUD_iwNga?dl=0 |

I managed to make a nice 15 second vocal recording, of the Soul Survivor's "Expressway To Your Heart" a couple of days ago. On my Warm 47jr. But I kept thinking how much BETTER it would have sounded on the BU67, after the playback.  Chris |

@vincent R.
They all sounded good. I do hear what you say about the slightly more open quality of the other tube and mic. But it (BU67) sounded closer to the Flea 49 in some aspects. It's a solid performer and a quality capture that no one would fret over the difference if we weren't comparing side by side. I'm guessing just a little EQ could make up the difference with little effort.

Hi there. I do agree that you have some noise there. it isn't a lot of noise but it is there. Have you tried the tube from your mk67 in the bu67 (assuming the pinout is correct) as this will help determine the source of the noise. also just checking your psi is switched to the 115v setting as the lowered filament voltage would also cause noise and cathode degredation. keen to know your findings. thanks ben mics Hi Ben, here is a comparison file I made, testing the BU67 against my MK67. It's just a spoken word test to compare the noise floor between the two mics. I set up the mics as close as I could. I made three test recordings, one with the BU67 in stock position, one with the BU67 in the 269 position and the last I swapped the stock EF86 tube for one of my low noise NOS Telefunken EF86 tubes, to eliminate the tube as the source of noise. For each BU67 recording, I spoke directly in between the mics for each phrase "This is the BU67" then "This is the MK67" recording both mics at the same time. I edited together all three tests into one file for ease of listening. I used a 1khz test tone from my phone to level match the preamp gain between the two mics. The preamp used was an RTZ 9762 (Neve style). Hope that made sense. Curious to know what others think. I would mainly like to know if this is an acceptable and normal noise floor on an otherwise fantastic mic? I'm sure it goes without saying, but this is a critical listening test. Headphones or studio monitors please.  drive.google.com/file/d/1ef7ZrFY6hG-YFlZfrPlrYTxFJwRHMK5T/view?usp=sharing any thoughts about a possible fix for my noise issue? |

The U67 and close clones all change considerably with a change in tube. The 60s Amperex and the Telefunken EF806s are probably the most celebrated. the 806s is a bit bigger on top and bottom whereas the Amperex 86 has a powerful and detailed midrange. And yet there are more options available! |

Derail!! Chris , I bought the 45 of Expressway to your Heart when it first came out in the 60's and my band played it; loved it then but haven't thought about it since. a good memory.
Cheers Ross

Here's that clip on the 47Jr for comparison below.
Among other things compared to the BU67 "Love Is All Around"/Troggs clip posted earlier in this thread...
1) BU67 is more balanced in tone.
To put it mildly!
2) More clarity (Warm sounds somewhat veiled)
3) 47Jr's capsule is "gritty" on my low notes.

This is my last ditch effort to try and elicit a response in hopes of getting some resolution on this noise issue. I would very much like to use this mic, but I'm afraid I'll have to move on if not. I'll give it one more week. The radio silence is as much of a bummer as the noisy mic. I'll follow up via FB Messenger, PM and email. That should cover all of the communication channels. Hope you hear from you soon, man! It's potentially a great mic! |

So so sorry. We have been heads down on production.
The noise in the mic is concerning.
I think I might replace it for you.
can you flick me another email tomorrow, I’ll get the ball rolling.
again, sorry that I didn’t reply sooner.
thanks

After all, is this mic worth it? Sounded great on Josh’s review. Has anyone compared it to the Ri? Thanks.

I bought it and think it was a good investment. Great sound. Affordable. Really sounds like a 67 yet has several options for tweaking. It hasn't disappointed me so far, but that doesn't mean it's the mic for absolutely everything. |

Isn’t that mike in classifieds now ? It is! I sold it to Indiehouse and now he has it listed. I hope no one misconstrues that as me not being happy with the mic. Over the summer, I picked up the BU67 and the Stam SA-47 to hold me over while Mr. Wheeler was repairing my Korby KAT mic system. Once I got the Korby back I sold the BU67 and SA47. I wish I could keep them all but my business over the past 2 years has shifted to about 99.9% mixing/mastering so it's hard to justify having too many mics around when I hardly ever track any more. I've used the Korby for probably 20 years now so I just know it so well that it's awfully hard to ever think about fully replacing it. |

It’s a gorgeous mic. I loved the 67 and 251 heads. My buddy had all the hotrodded caps. He even had a 49 cap that sent me on my 49 journey. Glad you got it back in working order. |

I never managed to come across the 49 cap, I'd love to at some point! I did have the C800 cap for a while. I currently have the 67, 251, C12 and 47. I always thought the 47 was the weak link but since getting it back in tip top shape, it may be my favorite now! I've done a lot of projects with worship teams at churches where there are multiple male and female singers and the Korby has just been a Godsend during those times to quickly swap between caps(they are hot swappable) and keep the ball rolling. I was a bit nervous about long term maintenance but since Mr. Wheeler moved to NC I feel much better about it! |

I bought the BU67 indiehouse listed (and previously owned by seawell)! Supposed to arrive tomorrow but no tracking for me for a couple weeks and no crooners there - I’m mostly metal/punk/hardcore/ugly music.
Probably ridiculous that I have a small army of tube mics these days for that sorta thing but I do like them and most of them (like most good mics) work well on a variety of sources.
Plan on trying the BU67 on drum overhead and guitar amps first. Happy to report back after. I’ll have three different projects that week!

Having listen to the various clips, it’s hard not to be very impressed with the BU67 - it feels like something of a bargain!
Does anyone know if BN make their own capsules in house in Australia?
