Hi guys,I'm looking for 2 25 amp 1 ohm sandbar resistors to load my power supply instead of a bulb. I was told they were Radio Shack items but my local RS says no got and not listed on their computer. Any idea where I could get them or another sulution would be appreceiated.

Go to Radioshack.com and search for part number 271-131.
What you are looking for is a 1 ohm 10 watt wirewound power resistor, sometimes called a sandbar or ceramic resistor. Try [link=http://www.radioshack.com/product/index.jsp?productId=2062290&cp=2032058.2032230.2032267&allCount=102&fbn=Type%2FPower+Resistors&f=PAD%2FProduct+Type%2FPower+Resistors&fbc=1&parentPage=family]this link first[/link], if it fails, then do the search on RatShack.
I would suggest using a single 10 ohm 10 watt resistor first. If your voltages are sufficient, then there is no need to load the PS any further.
