Ok, I will check into that. Why then is an op amp a better choice,
other than fewer connections involved, which is not a major issue. I
like solder.


JS Op-amps are just much nicer to work with, it's a one chip solution and
JS very versatile. There's TONS of info out there on using them, here's a
JS page for example http://www.northcountryradio.com/PDFs/column003.pdf


OTOH, an opamp IC has about 8 pins to make a connection to while a
transistor only has 3. An opamp is also easier to unwittingly have
oscillate than a transistor. Sometimes a one chip solution is a lot
more of a burden than expected of the novice.
