I bought some power transistors before I found out that the most common source of counterfeits is ebay. Yep, they were counterfeits. Seller in Hong Kong - lpcsunny2008. They offered a refund if I ship them back to them. They continue to sell the transistors even after they said they would stop.
If you do repairs on power amps - guitar or otherwise - get educated on this issue. Counterfeit transistors are typically smaller transistors that are repackaged or re-labeled as more expensive or obsolete transistors. The power transistors are the worst, since they WILL fail under load (they're not capable of handling the current), usually taking out other parts with them & causing you to have to re-troubleshoot the entire amp.
BTW, ANY obsolete transistor is a target for counterfeiting, so if you're looking for matching transistors for an old Boss pedal & can't find the part number anywhere but on ebay - BEWARE!
Stick with the major parts suppliers that get their inventory straight from the factories. Even your local parts house is succeptible to this fraud. |

That sucks that sellers like that are able to get away with what they are doing.
While it is possible to leave negative feedback and stuff, I think ebay should be more proactive about stopping this sort of trading.
Unfortunately, it won't happen until someone tries to sue ebay for allowing this sort of thing. I hope someone does! |

Rod Elliot (Elliot Sound Products - http://sound.westhost.com/ ) had this to say:
"I'd be really interested to hear from someone who bought transistors on eBay that were actually Ok. My guess is that probably 99% are fakes, and from China, make that 100%." |

I've bought 2SK30A FETs from Thailand expecting them to be crap, but they are completely fine.
