*** Neither I nor some of my electronic freiends can find the part number or the
transistor anywhere. If they are at a local electronic store, we can't find
it.***

***I can not find the Radio Shack part number (276-2043) in any store. I went
to the Radio Shack web site and they do not recognize the number. I went to the
store and they don't have a reference either. (Most of them know only what is on
the shelf....and I wonder if they know much about that.)***
