noise of arrays

[Haible_Juergen#Tel2743]

Hi!

Short question:
Does anybody know how noisy cheap transistor arrays (CA3046)
are, compared with cheap low noise transistors (BC550)?
The reason why I'm asking: I'd like to build this ARP all pass cascade,
and I wonder if I should use arrays or selected discrete transistors.
(please don't suggest expensive MAT arrays - the ARP cascade needs
seven of them!)

Thanks,

JH.
