73.3824MHz crystal

[Gareth Magennis]

Why can't I find, and why did Eventide use, a 73.3824MHz crystal to drive
the Master Clock in the H3000 series?

Cuh.

Well, perhaps coincidentally, it's 65536 * 44.100 kHz * 1.3000 for
oversampling.

Well, perhaps coincidentally, it's 128 * 44.100 kHz * 1.3000 for
oversampling.

Corrected binary divisor!

I don't have the Service manual in front of me now, but, yes, 44.1K is one
of the derived clocks.

I just can't get the crystal!
