I recently bought an old Allen & Heath System 8 1616, sixteen track mixer for decently cheap because it didn't have a power supply. After asking around online I figured it would be about $100 to $200 to either buy a replacement or have one built, the schematics are available. So anyway, I finally got in touch with the only electronics repair shop that I've been able to find in Atlanta, and they told me it could cost about $1100! Is this reasonable? The board was only $400. Does anyone know of a place online that will build/replace one? Or does anyone have any other suggestions?

You could always build it yourself. Not only would you save money but you would learn a new skill in soldering, learn to read schematics and gain some experience with VO meters and osciloscopes. You don't have to buy the O-scope a technical school or college near you might let you use theirs. If you can't do that try a HAM radio operator or just have an electronics shop tune it for you. You could build it on a breadboard and do point to point wiring instead of a PCB (a prototype PCB will cost more than the power supply) and then mount it in an appropriate housing.
Or you could spend $1100

Another option might be to purchase a Lab, or Workshop bench power supply - high quality Hewlett Packard types are always available on eBay cheaply - but a new one from an electronics catalogue won't be too expensive.
Ensure that you get one capable of producing balanced, or bipolar voltages (positive, zero volts and negative) - voltage +15, 0, -15 at up to at least 2 amps.
All you will then have to do is connect it to an XLR to plug into the mixer.
At a later stage you can add another supply to give you +48 volts for the Phantom supply - but you will have lots of noisy control potentiometers to clean before you need this.....!
I have schematics - if you need XLR pin numbers, or other information - but I am in the UK - so can help only via the ether!

that's why they sold it to you cheap... sorry, we all fall for that sometimes! On the other hand, you are in the right place and you may not be S.O.L yet. Maybe someone in this board knows what you need and will come to your rescue!
