[QUOTE="Terryl, post: 1007968, member: 369937"] If you have over heating problems with a power resistor then try locating some of these hummers.(in the correct resistance value) [URL]http://www.ohmite.com/cat/acl_hs1.pdf[/URL] And they are made in the UK, so they may be easy to find locally. What I do is remove the problem resistor and solder in some stand off leads, be sure to bend them down below the circuit board (or above) and follow the trace a bit to allow for a solid attachment to the PCB, then solder the new resistor onto these leads, this also allows you to stand it up off the PCB allowing for air to flow. They start at 5 watts so it may be overkill but it will never over heat again. [/QUOTE]
