[sdiy] Achieving through-zero flanging using 2 PT2399 echo IC's

[jpdesroc at oricom.ca]

Hi list,
Just an idea..

Using 2 PT2399's echo IC's side by side, 
setting a working delay of around 40msec
for the first IC and the other
swept from 35 to 45msec would it be possible
to achieve a through-zero flanging?
I think so..
What do you think of the idea?
The only problem I'd see is aliasing between them.
I just bought 10 PT2399's on eBay at $20.00
and think it's a good deal.
