I have a couple B67-269 mics. They are great and I use them on a lot of sources. For my uses, the cable is too short. Yep, I could just move the power supply with them, but frankly, I don't want to. I was going back and forth on getting some cables made but ultimately decided to make them myself. I sent a note to Ben, but I didn't get a response, and I'm impatient. :-) For anyone else interested, Here is some info you will want to know when making / buying cables. So, here are the pinouts:
The B67-269 uses a 7 conductor tube mic cable
All pins are 1-1
All wires are the same gauge in the original cable
Cable
1 White B+ (200v)
2 Blue Heater (6V)
3 Green Pattern 0-120V)
4 Yellow Ground
5 Red Audio +
6 Brown Audio -
7 Black Ground
Shield is only going to the shell of the connector
Power Supply
1 Red B+ (200v)
2 Green Heater (6V)
3 Blue Pattern 0-120V)
4 Ground
5 Blue Audio +
6 White Audio -
7 Ground
Pins 4&7 tie together with the connector chassis ground
Hope this helps someone else. I got both Gotham GAC-7 and Sommer cable. Both are nice. I would use the larger gauge wires for the heater and ground if using GAC-7. The rest are super low current <10ma.
Biggest difficulty is soldering it all up. 7 pin XLR connectors are pretty tight and not much fun to work with, especially with larger cable, like the ones I bought.

...but so worth it for that Sommer cable!

I agree, it is a little short for me too…thanks for the tip! |

So if you are making a longer one up do you want to take orders for doing some more at the same time??

How long does it come with, as stock?

Stock cable is 12'. It barely gets from my rack down to the floor and up a mic stand. I'm sure Ben had to cut some corners somewhere to keep these affordable. The cable is easy enough to upgrade. The mic sounds great too.

That's really helpful for anyone looking to make or buy custom cables. I can imagine soldering those 7-pin XLR connectors can be a challenge, but it's great that you were able to get it done. Did you notice any significant improvement in terms of sound quality or convenience with the longer cables? |

I have not been able to compare. My guess is that there will not be much difference. The wire gauges are similar except for the heater. The shielding on the Gotham and Sommer will be better than the stock cable, but I don't have any issues with the stock cable other than the length of the cable and the tight fit of the female XLR. The Neutrik 7 pin female XLR goes on much nicer. I'm not sure when I can do an A/B test. I blew out my back and I'm supposed to go on a short tour next week. I'm just working on healing at this point.

Sorry to hear that.
I hope things get better soon.
