"I purchased a STK-0029 from their website. Their datasheet says it will work for a PIoneer SX-580.
I purchased 6 of them for $ 4.50. None of them worked. UTSource asked if I would be happy for a 50% refund. Why would I? Their Datasheet specifically says it will work for SX-580 even though the ones they sent were STK0029 (without the dashes). They claimed it would work and was the same. I also had to wait 3 weeks for the part since China based. I am trying to dispute the transaction with my bank since they did not help me. I will never purchase from them again. I also purchased some transistors from them in the past very cheap quality. thin legs that broke on the T-220 transistor. I have learned my lesson. By the way I purchased the same power packs on ebay and they worked fine. Terrible Fraudulent company with awful customer service. Stay away find another vendor!!!!"

They do fake them though, by remarking. I got really bad experiences.

Hi Jestine. I do a lot of power amplifier repairs. I now a fake transistor when I see one. I actually crack them open and compare to a known real transistor of that part number, which I keep stored away for reference. The good one 2SC5200 & 2SA1943, have a silicon die of about 5,5mm x 5,5mm.
The fakes sometimes have little white die's the size of 3mm x 3mm. Obviously fake.
plPase see rod Elliot's article http://sound.westhost.com/counterfeit.htm
Im not bad mouthing anybody. I'm just stating the facts as I see them.

HI Riaan,

The first batch of products that I have ordered so far so good. Could you kindly share your real experience as this would be fair to Utsource. Sometimes one has to check the surrounding components before replacing a part if not then the new part that you have installed will not work thinking that the particular part is a fake.Thanks.
