[sdiy] BA718 and other obsolete parts..

[Seb Francis]

Hi,

I'm trying to recreate the Boss DC-2 Dimension C chorus circuit from the 
schematic but I'm having a bit of trouble getting the right parts.

I'm thinking it's ok to use an NE571 instead of the NE570
And I've read that a TL072 can be used instead of the M5218L

But I'm stuck on what to use for the BA718 opamps ..  does anyone have a 
datasheet about this opamp, or a recommendation of an equivalent?

Thanks in advance,
Seb
