Squeak - Squawk
What ever you call it... it
is annoying. Almost everyone of these units eventually
develops this problem. It is caused by a bad capacitor. I
found my first DH-100 of these about 3 years ago and it had
the offensive noise. So I searched the web for a fix and
lucky for me someone named Dorian had a page that described
how to fix the problem. I found another sax recently and
tried to find Dorian's page but it was no longer available.
So I am recreating it here for everyone to see.
I will have pictures someday....
Step 1 - Open your
Step 2 - Remove the top
circuit board and turn it over. The capacitor that causes
the problem is C39. It usually looks like it has leaked and
is a bit crusty.
Step 3 - Remove the bad
capacitor, you can either unsolder it or just cut the leads,
or if you are careful you can just rock it back and forth
until it breaks off.
Step 4 - Get a capacitor
(less than a dollar at Radio Shack) I use a 47uF tantalum
Step 5 - Solder the new
capacitor into the two small holes next to where you just
removed the bad capacitor from.
Step 6 - Put it back
together and blow until your heart is content.
I will have pictures
If you don't feel
comfortable doing this modification yourself. Please contact
me and I can do it for you for $35. email me at email@example.com
This fix will also work on
other Casio digital horn models DH-200 and DH-500.

Digital Horn you can get one here --- www.ebay.com
