I'm starting to plan my build and will use one of those Hifi2000 cases, and I plan on getting the front and back-panel machined with some cutouts so I don't have to drill those myself.
I want to include the following features in this amp, but this is the first time I'll ever be building an amp so just want to confirm a few things and get some help if possible:
* Standby/On switch at the front of the case with a built-in LED to indicate when it's on - for this I need a separate power supply right? Is that a 5V power supply?
* Will start with 2 channels in a dual-mono config with Neurochrome input buffers using the SMPS1200A400, but will eventually add a 3rd channel when I need it. For this I want to add a toggle switch to the front that will eventually allow me to switch between 2ch mode and 3ch mode. 2ch mode would turn off power to the 3rd channel.
* Use Neutrik XLR sockets in the back
* Use 5-way binding posts in the back that accepts banana plugs as well
* Have 2x 12V Trigger Inputs > these will need to be connected to the same standby power-supply that I would use to turn on the amp from the front button right?
Any suggestions for good online stores (US) where a lot of these parts can be bought, such as XLR sockets, speaker binding posts, trigger inputs, power switches / buttons, 5V power supplies, etc? Yeah there's always Ebay, but you're never really sure what you're going to get there.
