VH Audio I think sells one.
If Radioshack doesn't have it, most electronics parts stores or larger computer stores should. If you want a model #, try Startech.com
1 Ft. Monitor Power Adapter Model PAC100
It is a standard 3 prong female to male IEC adapter
And the answer is yes, it will work. Even on cords that you think are fully broken in. Use your refrigerator, not a computer monitor or box fan, your refrigerator. Stick it on the fridge and leave it for a couple of weeks.
Take a look at www.stayonline.com where the adapters can be had for $3 each. Shipping should be around $6 though.
IEC C14 to NEMA 5-15R Adapter
Also the adapters are only $12.99 on Chris' VH audio website and he is a really nice person to deal with. His powercords are very good value for money.
I actually just looked at the Startech site (had not looked at it before). That adapter should be available much below the MSRP; I purchased mine in Canada for $4.99 which is half the $9.99 Cnd on the site. Should be readily available in the U.S. at around $3-$4. I also own the VH adapter as well but it is around 5X the price when you factor shipping in and does exactly the same thing.
