    Hi

    I want to start this thread to find legitimate distributors for real transistors. I know the common ones like Digikey, Mouser, Newark and Allied. But They don't have what I want (2SC4883 and 2SA1930). I would like to get more names for future reference also.

    I want to keep asking on this thread when I get any new distributor names and post here.

    The first one suggested by Footfungus is Quest Components : http://www.questcomp.com/?gclid=Cjw...ctJ2FYpbXYFsMnA1jSowjfiFViHXJnMxxvhoCpUrw_wcB

    Anyone have opinion with this? If you have other distributors you can suggest, I would really appreciated.

    Thanks

    Any reason you aren't using the 2SC5171? Availability?

    It is also last time buy. I try not to change transistor yet at this point. Changing transistor always taking a risk of instability. I just afraid if I buy a few, test them out in the circuit and want to buy......and they are out!!!!

    Not in the US, but I've had good luck with-http://www.profusionplc.com/ for some things, though their selection seems more limited lately.

    It's very frustrating even the ones still in production can be temporary out and 12 weeks lead time!!! You never stock enough. I spent so much money stocking up parts already. I have enough for myself, but two members here want to build my amp, so they need the parts!!!

    Thanks Conrad

    They don't have the two I need, but I'll keep this in mind next time.

    I've bought from Profusion as well with good luck. Shipping is fast and reasonable given its international. Good deals when the pound dips.

    I've bought from Chip1Stop. The are an authorized distributor. The handle the EOL for Toshiba and some of the other Japanese companies.

    B&D is a solid choice. I wouldn't worry about anything bought from them. I think they were (are?) a Sanyo distributor, so they know the business.

    BTW, I ordered some 2SA1930/2SC5171 from Mouser. They are showing Aug 7 for the 2SA1930 and Aug 27 for the 2SC5171.

    Thanks Avionics and FootFungus, I ordered both 25pcs of 2SC4883 and 112pcs of 2SC4793. Ha ha, I added a few pcs to go to $100 and get free shipping.

    Received the 112 of 2SC4793 and 25 of 2SC4883 from B+D Enterprise:

    The following two picture is two of the 2SC4793, the LEFT is one I bought from Digikey 3 years ago when they have plenty in stock. The right one is from B+D I just received.

    B+D 2SC4793 1.jpg

    B+D 2SC4793 2.jpg

    Look the same to me in both angle. I think it's real. obviously the lot/serial number is different, the old one from Digikey is 4:Q, the one from B+D is 5:g

    Going to measure the Vbe and put in the circuit, if it works, it's all good.

    4Q and 5 G are simply production codes. They mean nothing as far as specs are concerned.
