phaser using ota's , and matching between stages

[Peter Blackett]

Hi,
I'm thinking about building a phaser using the Ca 3094 ota , along the
lines of the Moog stage phaser , and was wondering how closely the
capacitors needed to be matched in each stage ? the caps are 1nf value.
Resistors I can get in 1% tolerance .
Farnell do have the Ca3094 available ....
any suggestions would be welcome.
