hello,

the blacet time machine uses two internal filters, one at the
signal input (to get rid of aliasing) and one at the signal output
(to remove the clock noise). i believe that both of these
filters have a 30db lowpass response. so if you want to
get close to the time machine sound you would need the
a188/1d (4096 stages) and two lowpass vcf's (the steeper the better).

often the filter at the signal input can be omitted, because
it is a matter of taste (and how the input signal looks like)
if the aliasing is problematic or not. but you will for sure
want a filter at the bbd output to eliminate the clock noise
when using long delay times.

and of course you need a vca or vc-polarizer in the feedback
loop of the a188/1d to get voltage controlled feedback.

best wishes

ingo
