Ok so a family friend who owns a drum rental company was getting rid of some things and he had an old mixer that he gave me but i don't have a power supply for it and i don't know if he has it either. The mixer is an old Lamb Laboratories PML422 and it has a weird connector for the power that the only thing it looks similar to is the power supply on my school's mixer ( a small Alesis unpower mixer) and it has 7 prongs. So would i be able to find a way to power this thing without spending an obscene amount of money? I don't really know much about mixers but i know that most pedals use the same voltage, so is there some kind of "standard" mixer power supply that is used? I couldn't find much on this thing on google so if anyone has any input, guesses, or advice i would be happy to hear it. Below (hopefully) is two pictures of the mixer.

Where can i get a power supply for my mixer?

Hi.
I have no experience about that particular mixer, but it sure is a beauty
.
Congrats.
AFAIK/IME there's no standard as far as the connectors go, every manufacturer tends to choose the rail voltages differently and at least the pinout differs as well even if the rails are the same.
You may be able to reverse engineer the connections for PSU, but without a schematics that will require quite a bit of time.
Given the amount of pins, it's also unlikely that You'll be able to fabricate the PSU using just one transformer, and that creates additional problems as a hum-free operation is a must. Obviously.
The connector itself looks like a bayonet DIN, easy(ish) to find.
Good luck.
Regards
Sam

I found an old eBay auction via Google that specs a regulated 24volt DC supply for that piece, but not at what current. Personally, I would call or email Studer and also post an inquiry at ProSoundWeb.com in the Lounge section.
One of the only search hits is a YouTube vid put up by a guy who owns two of these. He's already answered a couple of questions maybe he'll tell you amperage.
Don't bother, unless you have a friend who knows about this stuff and owes you a favor or three.
Not exactly a useful mixer in the first place, and IF you manage to get it powered will it even work? Looks pretty old and dusty...
Will it fill a particular need you have?
Doesn't even have XLR inputs--more of a DJ mixer if you ask me.
Just dump it on ebay and save yourself the headache.

Ok well i posted a little comment in the doo dader on that youtube video and asked the guy who i got it from to try to see if he has the psu in one his warehouses or his garage/basement. Also it does have xlr jacks, it was made mostly for studios from what i know, and it was being used in a studio before the guy who gave it to me got it, so there's a decent chance it will work.
I suggest asking your family friend if he has the power supply and patch cord.

Wow those pictures are very useful, with those combined with my knowledge of the internal circuitry i actually have a good shot at fabricating something if the original power supply is gone for good. Thanks!
Well i actually did get a power supply for it hooked up, i managed to wire a variable voltage laptop power supply (set to 24vdc) to a standard power jack i installed but unfortunately most of the pots and switches in the mixer were broken so i got a new mixer since the cost of replacing the components would have been more than the price of a new mixer.
