MAD1108 and matching parts

[Peter Blackett]

Dear Tom,
I think a way of matching parts would be great , for those who can't get
hold of some of the altready matched parts .....
I'm thinking of making a phaser using ota's [ Ca3094  ]
and I decided [ with advice from people on this list ] to use 1%
resistors and caps for the network.
but other people on the diy list suggest that I now need to match the
ota's .
anyone know a schematic to do this ?
