An original moog filter like the minimoog has 24 dB-lowpass-filters, a four time special tuned cascade of 6dB.
the TB303 has a rebuild 3 cascade with 18 dB., which have lite other tunings and another saturation.
The particular of the A-102 is the dependence between emphasis and cutoff, there are modulations between the
two components by tuning one of it or both.
It is not the same as the A-103, which is a rebuild of the TB303 filter.
If you ever heard of or worked with an EMS Synth, you would know the difference between these filters.
I'm not a technician, but I have good ears and know both.
The A-102 will be a very special filter with a very good and different sound to the TB303, believe me!
best regards
