Reliable Ebay parts suppliers?

[spooney]

Are there any reliable parts sources on ebay? I am trying to find a pair of outputs for an amp I have. I need a 2SC5198 and a 2SA1941. MCM has them but wants 9 dollars to ship two transistors. On ebay I could get 4 pairs or more for the same price. I really want to make sure I get a good part but am unsure of the integrity of the ebay parts and suppliers. On another note does anyone know if a TIP35C and TIP36C would work as a replacement?

I've had problems with biasing when using the TIP35C and TIP36C in place of the 2S transistors. They can be used but you have to test to thermal shutdown and likely will have to modify the circuit.

I've been using the FJA4213 and the FJA4313 for all of the 2S transistors in that case style. I've never had a problem with reliability or biasing.

The FJA4310 and 4210 will likely work in your amp if you can't find the ones above.

I might have a set of those still. We will see. If not I may bite the bullet and buy the originals.

Well I am all out of the FJA4210 and 4310. I've found the FJA4213 and 4313 at digikey but they have two versions. They have the FJA4213RTU/FJA4313RTU and the FJA4213OTU/FJA4313OTU. Only difference I see between them is current gain. Does it matter which one I use?

Personally I wouldnt touch ebay for components.
I have no idea how old they are or where the components come from.

I stick to top quality vendors, at least I can complain to them if there is any problem and I know they will rectify it.

Got an empty packet from one vendor last week so emailed them and the components were here next day.

When it comes to transistors and Ebay(I sell and buy on Ebay) I buy my Transistors from Tech diy here on the forum , or digikey,mouser, and for hard to source parts audiolab in Geogia,USA . Common stuff like IRFP's for drivers and such Ebay is not too bad ...Let the buyer beware you can get fakes from good suppliers.

I found I have to shop around the best vendors for a good price.

i.e. An irs2092 was £10 from Farnell but £3-17 from Future Electronics.
But you do have to watch for p+p charges which can sometimes be significant.
I like RS Components as they have no min order charge and dont charge for p+p.

I have never had a problem with Ebay vendors. I always look for free shipping, and I always deal with a vendor with a large sales number. If a vendor has sold hundreds of items and has a good track record, then that's a pretty good indication of good product & service.
