Hey, thanks. I don't believe so. I been around a lot of mics for decades. I mean it wants to rip your ears off in the 5-7khz zone. It really sounds like a tight capsule. Although... you been there with this mic. You really think the tube could make that much difference? I've heard a lot of people say they swapped for NOS tubes and ended up using the stock one. I’m sitting here with the new MK67 kit with the new reissue mode (which is really nice and more open than standard vintage mode) and a Neumann BV12 and worrying that I will feel this exact same way if I change the transformer. Lol. bowie sells some nice NOS tubes though. We were talking about a Mullard EF86 that might be the trick for what you’re looking for. I'm in the exact same boat as you, Vincent. My initial impressions are the standard mode on the MK67 doesn't sound as dark as I had expected based on the clips I had heard, and the reissue mode is actually kinda bright. I've got a Neumann transformer on the way but now I'm worried it might make the mic too bright. I need to use it more extensively to make a decision.

I think there's a basic misunderstanding of the tech here. The Neumann transformer IS the fix. The reissue mode is a band-aid, or a color option offsetting whatever the MK67 current transformer sounds like, whatever you want to call it. There's technically nothing else different between an MK67 and a reissue 67 at all other than the transformer. The MK67 transformer has likely been tweaked, as many as have been sold. I would certainly hope so. With a Neumann transformer, you will not use the 'reissue mode' again. Remember KLAUS FOUND NO FAULT WITH THE REISSUE PREAMP ITSELF! THAT SHOULD BE THE #1 POINT TO REFERENCE!

THAT SHOULD BE THE #1 POINT TO REFERENCE! No I get it. It's just after having this specific MK67 in my hands and using it I'm wondering if it's still necessary to change the transformer. Like you I'm suspecting that Max tweaked the transformer after the public consensus seemed to be that his was a bit too dark. Then adding the reissue mode gives another, brighter option when the mic is still too dark. I've already bought the Neumann transformer so I'll probably still have it put in the mic. But after my initial testing it doesn't seem as necessary as I had thought it would be based on the clips I had previously heard of the MK67. People saying their 67 RI is ripping their ears off gives me further pause lol. I just got the mic so I really just need to use it a bit more before changing anything on it. I'm still using the stock "premium" Valvo PF86 tube that was included in this batch as well.

I'm still using the stock "premium" Valvo PF86 tube that was included in this batch as well. Ive not heard of people saying the U67 RI is ripping their ears off. First I’ve ever heard someone say that. Also, I found my PF86 to be much brighter in the sibilant range than any of my EF86’s. I’d start with a tube swap.

First I've heard of it was on this thread too. I've only tested the MK67 my voice so far but sibilance was definitely not a problem with it in regular mode. In fact, it might be the least sibilant mic I've ever used on my voice. If an EF86 is going to make it darker I'm not sure that's what I want. I guess my point here is I don't want to start swapping out tubes and transformers before I've even identified anything I don't like about the stock tube and transformer.

And I wouldn’t say a tube swap made the mic darker.

If an EF86 is going to make it darker I'm not sure that's what I want. I wouldn't say darker, more that it brings in the bass, fills out the bottom. I found the PF86 I had was the thinnest sounding tube of the half dozenish I had on hand.

I've got a Neumann transformer on the way but now I'm worried it might make the mic too bright. I need to use it more extensively to make a decision. I actually find the standard mode of the MK67 to be dull. I totally understand why people like it on super sibalent voices, but I find my self boosting alot with EQ and carving out the low mids. I like the Reissue Mode. I don't find it to be bright, but haven't done and crazy testing yet. In the testing I have done with it I found it only a little bit more open, but has a dip in the low mids. The Standard Mode as a low mid push that isn't in a real U67. Reissue Mode is, as EmRR says, a bandaid that helps with that.

The PF86 mine came with is a little nasal by comparison to the EF86 I put in.

I had an order from Mouser going so I threw in the cap to do the reissue mod on mine, I've had it for 4+ years and never bothered with the linear mod. I dig it (with a Telefunken EF86 currently) but you guys got me curious to try the Neumann transformer and not bother with the mod.

is there a direct sennheiser usa link for the transformer ? or are people ordering from the UK ? I have a max du67 and a du67 with a Moby bv12 would like to try the original

You can order from the UK or pay a markup and order from a US retailer.

My transformer just showed up and I've got the newer cap here as well. Anyone here install both mods? If so what were your results?

I have a max du67 and a du67 with a Moby bv12 would like to try the original Generally speaking, if I already had the Moby I would go with it and not look back. It is extremely close. When I commented to him about the differences (Neumann more mid-centric, Moby slightly more sparkle and bottom, very hair-splitting) I was told he was aware of at least two winding revisions, and he'd picked the slightly brighter one. True? Dunno. You have two mics, sure, try the Neumann. I really gotta wonder with a non-Neumann CAPSULE how far all control elements are out the window; probably pretty far.

I have a Neumann K67 and painstakingly swapped it between the max mic and the Moby /AMI bv12 mic .

The PF86 mine came with is a little nasal by comparison to the EF86 I put in. The PF86 has 4.5v heater and EF86 6.3v. As such they are not interchangeable without heater adjustment.

Ah, it's too involved to really cover it again. A guy who works on mics has been having issues and let down a bunch of people. Hopefully, he's getting better.
