RE: Working on my old guitar amp
Interesting thing about the three prong computer power cords.
Today, they are ubiquitous and standardized across the world.
And every electronics person has a bazillion around their house.
When this amp was built, the things didn't even exist.
Now, i wish for a proper standardized DC plug for a LED lamp.
So i can run a DC powerline straight from the backup batteries instead of converting to AC, just to convert it back to DC.
The only problem that I see with running straight DC for your lighting is the size of the wires you need to run 12 volts any distance without power loss. Converting it to 120 volts AC allows you to use reasonable sized wire and run your wires further without line losses. AC also doesn't arc in a switch the way DC does when you turn on a circuit with a load. Of course, that's not a problem when the load is a couple of LED lights, they don't draw much power.
