Just a note-  National semi is real good about free samples. They
have 1949's now - at least they finally got me mine. The things
do the 1/4 current back off for hold current - which I don't
think the '51's do.

Try
 National Semiconductor

<BR>you can run the National LM1951 1Amp driver. It has the built in zener,

<BR>or something of that nature.
