IMPORTANT NOTE:
I have stopped this group buy. Please do not ask me if you can buy a bunch of BC550 or BC560 transistors.

------------------------------------

This is a group buy for BC550C and BC560C BJTs. These are the "original" OnSemi/Fairchild parts, which are now obsolete.

Some hFE readings and curve traces are attached (I used a DCA75 tracer for this, so it shows only the low voltage/current part).

The BJTs come in bags of approximately 100 pieces. Each bag is CHF 20.00 (shipping is not included).

To sign up to this group buy:
(1) Reply to this thread with a complete copy of the list, and add your diyAudio name and the number of bags to the list.
(2) Send me a PM with your full name, shipping address, telephone number, and PayPal email address.
(3) I will send you a PayPal invoice.
(4) Once I received your payment, I will send the BJTs to you.

Note: this is a first small round for the group buy. I have only a few bags at the moment, because I ran out of packing materials. Depending on how this goes, I may consider doing another round.

I did not run out of transistors.

I ran our of packing materials. Also, life is happening and I cannot spend as much time on this as I'd like. Once I have the first round packed up and know the size / weight, I will figure out the shipping. After that I will inform everyone about their final amount and send payment instructions.

Guys, Mouser has new stock of On Semi BC550CBU at $6.10 USD per 100.

The PNP BC560C is harder to find, but still plenty available from specialist sellers who deal in obsolete stocks, particularly in the UK and Europe. Expect to pay 2 to 3 times more than the still available NPN compliment.
