Working on my Data East Sound Board REV 520-5002-01.
I am curious if anyone can tell me the size capacitors used at C1, C17, and C38. I replaced them in hopes to reduce some noise coming through the speakers and they looked to be original 25v 470uf. So I got new ones to replace...
However, after looking at the data sheet for the Sound Amp chip (MB3730A)...it looks like these should be 2200uf? I was hoping someone could take a peak and see what they have installed....I included a pic of the data sheet.
Thank you,
Jim
