Bucket Brigade Chip(s) Needed For Webelo Projects

I need to acquire a couple of "bucket brigade" IC chips for my son's
Webelo troop. They are in an endeavor to attain some of their "activity
badges" and my son has chosen electronics (which he has shown a great
deal of talent in). He has done quite a few projects on his own but now
is taking a leadership role in helping his brother Webelos put together
an "Echo Chamber".  If we can acquire these pieces he will be able to
complete the schematic he pulled off of the web. So if anyone can help
us (him) out it would be greatly appreciated. Also any messages with
the history of these chips, and other erata with regards to "Echo
Chambers" would be greatly appreciated. Thank you for your time and
consideration in this project.

Bill

Nobody seems to be making bucket brigade chips anymore.  But try a
search for "surround sound chips" I believe some of those could be
used to give you the delay.

You are probably better off with one of these :
http://www.darisus.de/Elektonikshop/Datenblaetter/Princeton/PT2399.pdf
They are easier to find than BBDs and sound better and cost <$10.
If you're dead set on BBDs, however, the numbers you should be looking
for
are SAD512,SAD1024,SAD4096,TDA1022,MN30xx (where xx = 05,07,08,etc)
These can be found at specialist fx pedal sellers, ebay, old Roland
bits etc

Note Rockby sell a chip that does audio delay, the SM7183. Echo from 20mS to
180mS.
There is a data sheet available by googling Sam Hop. It has applications.
