I dont think you need to match the ota's.. each ota stage funcrtions as its 
own all pass filter/ shifter.. so if they aint matched maybe one will have a 
few degrees more shift than another at times.. does it matter? I made an 8 
stage phaser with LM13600's [4 of them!] and I used standard 5%res, 10%? 
caps, chips bought straight from the shop and shoved straight in.. sounds 
far better than the fet phaser I made where I carefully matched all the fets 
etc..
Cheers,
Dan
