says they are used. fyi

ggetzoff · 7th March 2010, 03:55 PM

Yes, it does, but also said tested ok, and will replace if no good.

AndrewT · 7th March 2010, 04:19 PM

I don't like the seller's warranty conditions.
They exclude shipping and handling charges and you have to return the faulty FETs.

Sure, well every purchase off of Ebay is a gamble.

At least these guys deal in surface mounts and have perfect feedback. With a name like sisitronic, how can you go wrong?

I am not claiming at all those 2SJ109s are not genuine.

There are these days MANY companies who claimed to be registered in Hong Kong. In actual fact, they are nothing more than that, a registration and an address, with no real activities in Hong Kong. The actual operation is 99.9% in China. The reason why they want a registration in Hong Kong is that HK still has law and order, and respect international laws and copy rights.

I always treat those companies as suspect. Lately we made an enquiry in HK for MAX9401. Someone in China replied by email saying he had them. But he did not even quote the right package. When we asked further, there was no reply. So we avoid any direct purchase from China.

It is a real pity, because a few bad sheep will ruin the reputation of the entire country.

I think it's more than a few....it seems, to me at least, to be systemic and SOP for most "audio" offerings from China that appear on ebay.

We have bought audio products from China, like the QA550 SD player, and are perfectly happy with price, quality and after sales service.
So it is too easy to generalise.

11.50 for a used one is a bit steep.

ggetzoff · 01:31 PM

Well, I'll let everyone know where the package actually originates and if they are good parts.

As far as the price, yes, it's high, but $21 a piece from a vendor I found in N.J. or 19 from G.B. is even higher-

Does someone here know of a good 2sk74 source?
