IEC to a 2 prong-wire amp

I've also done this. The only difference from what Albert said is I bought a nibbler tool from Radio Shack (I think they're about $10). It "nibbles" out chunks of sheet metal - one at a time that are approx 1/16"x 1/4". Since I centered the IEC recepticle over where the old cord was, I didn't have to drill, simply began nibbling from the original hole out. I finished with a hand file (the nibbler leave ragged edges and went to go real slow for the final fit so I didn't cut too much out.

You'll want to be careful that metal cuttings don't get lodged on circuit boards and creaqting a short.

I also left off the ground wire . . . same rationale as Albert's.

Sounds simple enough. I do have lots of power cords that are collecting dust so might as well put one to use. I would like to know if the IEC is coded so one will know which end is which?

I use a Volt Ohm Meter and select continuity. Putting one lead on your power cords AC plug end and the other inside it's female IEC, you get a "beep" when you match up both ends. Make note of what goes where.

Next test your household wall outlets. They are marked internally as hot and neutral. If you don't know which way yours are wired, use the same VOM to determine.

Put the hot lead (red) in one vertical hole and the ground (black) in the round ground hole. If you read 120 volts, your red lead is connected to the hot. If you get zero you found the neutral.

Match that with previous results of beeping out the IEC and you have everything labeled where it goes.

As a personal note, I find it easier to draw a picture of the IEC results and where the hot and neutral are in the wall socket. Saves brain cells when your in the heat of soldering or trying to figure out what to connects to what.

if you're referring to polarity, it's likely that the IEC will indicate "N" for nuetral; "L" for live, "E" for "earth" , or something similar. I'm looking at one now and that's how it's marked. If it's not, the Live pin is on the left side if you're looking into the receptical where the cord plugs in, with the ground pin on the top.

I'm still playing around with this idea. I am wondering if the silver solder at radio Shack is good enough. I thought maybe down the line I might want to tweak something more expensive. Also has anyone tried the new battery operated solder gun?

I'm thinking for buying the IEC from Audionut. is there a difference in quality?
