Casio CZ/ VZ/ FZ - Pro Series

Are you still looking for info on the Sanyo LA4138?

Well, it just so happens that I took apart a non-working Peavey Midi 
Manager, started searching for info on parts, and stumbled onto a 
website in UK that will allow individuals to download up to 10 pdfs 
per day. 

They also have limits on the number of "Guest Views:"
Maximum Guest Views Per Day: 50
(So, shhhhhhh---don't tell too many people!)

Here's the link to the la4138 pdf download page
http://www.datasheets.org.uk/search.php?
q=la4138&sType=part&ExactDS=Starts

Or, go to http://www.datasheets.org.uk/ and type in la4138.

Hope this helps.
