Is there any disadvantage in using a TL072BCP instead of a TL072ACP??
(The BCP version costs about a nickel more, but has half the voltage
offset.)

Does anyone know a good source for nylon PCB mounting hardware??  I'm
looking for 4-40 hex threaded standoffs and nylon screws to use with
them.  I'm thinking that 3/8" standoffs with 1/4" screws will work,
unless someone thinks another size would be better.  I can't seem to
find a vendor that sells them at a reasonable quantity and price.

Does anyone know of a source for polystyrene caps??

Thanks :)
