thats friggin AWESOME! too bad the TLM is so damn expensive....8( that one that went for $1200 looks like a freakin steal now!!! Hell I'm kicking myself for passing up a 87ai at the store for $1500 cnd a couple years back. What's the permanent price going to be?

What's the permanent price going to be? he's probably going to end up offering it through chungs store in a more diy format, so? He's a friggin badass though, how cool is this idea?! It's essentially a real U67 for about $2k

well buy the kit and wait till you find a deal on the TLM ! am I missing something. Did he state somewhere that he won't be doing these kits for long? If you already own a tlm67 you had to have just wet yourself. No joke.

Thanks for the interest guys - yes plug and play, just a few screws, no solder etc. Will post a how-to shortly. I plan to build more of these at a slightly higher normal pricing after the initial batch is sold out.

If only I wasn't beyond broke

Looks like Max took the Innertube Audio approach to the U87/U67 retrofit mod. The inner tube though doesn't aspire to U67 emulation. It's it's own thing. Sounds kinda like a C12 and U47 had a baby.... Max - care to elaborate on the SOUND of YOUR unit? Vintage 67 (i.e. dark and smokey) or, modified 67 (bright but still neumanesque)? Or something else? If vintage, do you have any clips of a good condition Vintage 67 compared to your baby? In other words, how close IS it? 67's vary so widely due to so many of them being modded over the years. IMO, the traditional 67 sound is the last nut to be cracked by the emulations and I'm have been spoiled rotten by the 15+ KILLER vintage sounding 67's @ Capitol..... If it can attain that well conditioned vintage unit that sounds like it should status, you've got a winner. Also, does it work with Vintage and Modern U87's or just modern AI's? I know the pinout of the head basket changed with the AI I believe. Interesting though. The inner tube mod is off the hook, but if I could make my vintage 87 sound like an 87, 67 and Innertube monster in the matter of a few moments, that would be a pretty cool deal..... (BTW loving the MK47 here at last after getting rid of that resistor,,,,,, :-) PS - do you have any pics of the inside of the Power Supply? It looks like a cheap Chinese unit, and I'm hoping I'm wrong. Hoping for it to be better than that.......

Again, thanks for the kind words everyone!
Bill,
the build is taken directly from the original schematics/blueprints, and i did comparisons with a (unmodded) U67 in pristine condition to veryfy that it's spot on. The key-component is, how so often, the transformer which i wind from the original blueprints here in my little workshop. It employs all the features found in the original - including the feedback winding AND the innerwinding shield. Furthermore i took care of all the little details in the circuit, like the polystyrene feeback capacitor C17 etc - nothing is changed from the original except the ad-on of using either a PF86 or EF86. The Psu is indeed of chinese origin, but re-build to the original schematics by myself to provide the nescessary voltages of 210VDC and -6,3VDC which it does flawlessly. -Max

Just what I expected and was hoping for. One last question re: Pinout on the head basket. Is it set up for a Vintage 87 or the newer AI version? And if AI version, will you do a version for the Vintage Headbasket? I know that they are NOT interchangeable, as Stayne @ Innertube has told me that the guts of his mods for the 87 are identical, but the pinouts of the head basket changed, so I had to get a different retrofit from him as I was sold the wrong version for my vintage 87. It actually powers up with the wrong version, but sounds bizarre and the polar pattern switching is all off. Thx! bp

U87 and TLM67 have different caps don't they?

Post by ioaudio on Dec 7, 2014 16:31:59 GMT -6
Oh yes, i forgot about that - or just assumed that no one with a vintage U87 would make that mod - i would have to make a special version for it!

Well.....I think the vintage 87 and a vintage 67 are kind of worlds apart, so yes, I think guys with vintage 87's would be interested. The physical pins are identical and you can put the and AI cap on a vintage preamp body, but the WIRING to the pins is different. I think all that's required is re-wiring the wires that go to the head basket connector, but hey, I'm no tech.... Let me know if you decide to do this as I'm very interested. Good luck with it. bp

It should be possible - I'll research (also the XLR connector differences) and come back to you.
