helping hands???

["Liebig, Steuart A." <LiebigSA@Maritz.com>]

i have a friend whose eh 16-second delay just developed a nice hum (there
was a really nice high-pitched squeal that lasted about 10-20 seconds 
during
a set break, capacitor death?).

anyone have any ideas about people who are competent to fix these thangs?

thanks,
