Title: DE Secret Service "Humm"
Post by: FrizzleFried on April 13, 2009, 03:16:15 pm

My DE Secret Service has a distinct HUMM coming from the speakers... common?  Anyplace to look to rectify the situation?

Thats normal from a DE machine.

Some are louder than others, have a few shots & you wont notice it  8)

Now that I know it's normal I'll have no problem ignoring it.  I am married after all...  :cheers:

Here is some info on this problem:  http://www.pinrepair.com/de/index3.htm#sound

I would check your ground connections.   If this doesn't work, I would try recapping your sound board amplifier capacitors.
