[sdiy] Aries Multimode filter

[Robert Leiner]

The first digit can be a bit hard to read and options could be 8B or BB as
Mike suggested "The BB3500 is nothing but an old Burr-Brown 3500 high
slew-rate op amp that CFR liked to use. Haven't seen any in many years, but
there are others that could sub for this one if need be."

What could an replacement for "BB3500 Burr-Brown 3500 high slew-rate op amp"
be?

Ken Stone suggested that 7435 is almost certainly the year of manufacture
for the chip. The rest is probably an in-house code.

Keeping this on the list so others can participate! and for the record.
