I have a small supply of new old stock 2N3553 NPN transistors I'm
offering for sale.

You can see a datasheet on the 2N3553 at:

http://www.oselectronics.com/downloads/2n3553.pdf

I'm selling them in lots of 10 pieces for $22.00 INCLUDING DOMESTIC
SHIPPING. There is an additional $2 charge for overseas shipping.
===========================
In the UK the 2N3553 is available for GBP 0.95 each
,slightly cheaper than above with P+P paid.
