[QUOTE="mafioso, post: 283640, member: 572"] There's an invaluable knowledge base on this forum... :) @Hi-phibian I've looked inside a few of these s/m PSUs and noticed the small toroids. It's difficult to see all of the bits inside the PSU I'm now using as the works have an aluminium cover doubling as a heatsink over the bits. Do they all have the little toroid? The brand I'm using is Croma (with a line over the "a"), made in China of course. This is also the first one I've seen with a ventilated case. I wasn't too impressed by what I saw inside. Some untidy soldering on the pcb, scribed scratches or marks on the folded aluminium cover inside and a piece of a cigarette box cardboard shoved between the transformer and the aluminium cover...I guess for R180.- one can't expect more but it does the job. mafioso [/QUOTE]
