delay chips and design

["Lance Chance" <lrc8918@louisiana.edu>]

ok. so the bucket brigade chip is actually a true analog chip that was in
use in the 70s and 80s and now is in use in the moog analog delay.   would
these work?:
"SAD1024
1024 stage, capacitor "bucket brigade" audio frequency delay chip.
Discontinued, but Panasonic makes a full line of (apparently) equivalent
chips in various sizes and configurations. Three that may be suitable as
replacements are MN3007, MN3207, and MN3214. They are listed in the **
current ** DIGI-KEY catalog (199901..03) on page 187 at $9 to $18. The data
book is listed as part number 9102B at $3.50"
next question: does the EDP "read samples" like the repeater and if so why
does it not have a "pop" at the loop point of a looped sine.  does the line
6 "read samples" and is it's behavior more akin to the repeater or the EDP?
how prevalent is the repeater design architecture becoming in the
delay -loop market?
