Neumann U87Ai to MK67 mod how-to 

Thanks for this great Video! I received my MaxMod in 2018. I swapped out the TLM67 guts for the MK67. Ive also used Telefunken ef806s and ef86 tubes with it. Ive used this mic several times a week since I got it from Mr. Max Kircher in mid 2018. Its works great and it is an absolutely beautiful sounding microphone.

When I first considered that you were "modding" a U87Ai, my thought was "who would do that?" But, seeing as it's non-destructive and quickly reversible, I like the idea a lot.

Any idea what's the difference between the tubes?

Thanks for doing this video. I'm right on the edge, very tempted to get this mod. My main concern is self noise of the circuit.

hey can you make a video if how it sounds?

I want to buy one where can I get it

Could you do a Video of the tube replacement?

Hi, thanks for this video. How about the sound? I read that lot of guys who order this nice U67 plug in has the problem with the transformer sound and replace it with Moby U67 transformer. I heard the samples and the stock one sounded really dull.

Thanks for the video. How can we buy one?

Great video , Does he send a power box too with the insert ?

Where can I purchase this mod and would I need an extra external tube amp
