need 3Sk164 and 3SK166

Hi,
i need the sony devices which are obsolete now,
3SK164 and 3SK166.
Please, does anyone know where I can get may be 10 of them.
thanks

A quick search on 3SK164 using www.google.com gave the following results:

http://www.find-ic.com/partlist/3SK164.htm
http://www.nowcomponents.com/item1/page.cfm/464

and several other hits.

Thanks VSWR.
However, which ever i tried have some minimum purchase requirement of greater than S300 US.
I need only atmost 10 of each:(
