Ah, that's why it wasn't working. I tried to check Princeton's website for
data sheets on their delay IC's, but it was down as well
(www.princeton.com.tw).

>My circuit uses the PT2399, not the PT2395. The difference is that the
PT2399 has 64K memory built in, the PT2395 requires an external DRAM chip.
You can get >longer delays with the PT2395 by using a 256k DRAM. I wasn't
able to get a circuit working, with the PT2395 however. I was successful
with the PT2399.

Good to know.

>Also, the minimum delay is about 30mSec which sounds longer than you
wanted. It's really meant for an echo unit, not a chorus/flange.

Sooo...no good for my applications. Imagine that, Harry, a BBD may actually
be BETTER than a digital delay IC at something....lol!!!

What are the options for 5ms delay or less? There must be a crazy thing out
there used for filtering high frequencies for HAM nutters, or somesuch, that
would work, neh?
