i had an 80's Walker Mixing Console givin to me without a power supply here are some photos - any leads/help?   

does m-audio fasttrack act as a power supply for a Microphone?

I have a Fostex 2412 mixer (EU version) at home, and it is missing its power supply. I have searched over the web but nothing really comes up. Does any one know of a replacement or have one lying around they are not using?
attached is a photo of the power connection.

Thank you

Another first for me here.

I have 100 ft run to the piano. Using Mojave MA100's SP for the first time. They come with its own PS. The micpre's have 48v too. Do I use one or the other or both in a long run or longer runs? Do you ever need to use both to ramp anything up lada lada lada?

500 series preamps are a pretty popular item for discussion around here. I thought I would start a thread on the racks that hold these units. I'm going to give it a go as a first shot and as new or better information comes in I will edit this first post to try and make a pretty comprehensive list of options.

I have an old Groove Tubes 6TM mic with the PS1 Vacuum tube power supply. The mic end looks like the Groove Tubes EC7 cable in that it has a 7-pin connector. The power supply end looks like an 9-pin ADAT sync connector almost like a vga computer display connector. I am in need of the pin out configuration so that I can build one or a source to purchase one.

What are the benefits of relocating the power supply from inside a piece of gear and into it's own external box? Electrical interference reduction maybe? I've notice a number of really high-end preamps having this feature.

The 1 month old APC backup unit employed on my studio failed twice today, once last week. Yes there are shoddy power issues in the building. We have multiple breakers in our sub-board but haven't popped. These issues are for the electrician.

I Have a M-audio Sputnik microphone, but the problem is, that i don't have a power supply for it, which is a big problem because it is a 7-pin multi-pattern large diaphragm vacuum tube condense microphone, and there is no way to get it I live in Czech republic and here it's impossible to order it.

I am trying to improve my 200VDC power supply by making a simple linear regulator. nothing is ever simple...
