hi, i had a humming noise problem, too. it was a lot softer when i took the top off. by putting some isolation , i made sure that the top of the case wouldn't touch the transformator. the noise is still there, but it's a lot softer now. somebody told me that the humming is stronger when using the edp with 220 volts. seems that the trafo is ment to be used with 110 v. all the best, tilmann ----- Original Message ----- From: "phill wilson" <blackface@hotmail.co.uk> To: <Loopers-Delight@loopers-delight.com> Sent: Tuesday, March 27, 2007 3:28 AM Subject: EDP noise help (unsoldering) > Hi all > > right, ive gone and been a silly chimp, > I bought a second edp l( blackfaced echoplex)last month, but have been >so > so busy ive only just got to the pluggin in stage and.............. >aaaarh > noise!!! > hummming noisey noise.... > the humming actually starts as soon as the mains cord is plugged in and >is > raised to crazy levels as soon as i power on. > the screen displays correctly and all seems in order under the hood,and > ive tried all the normal fixes. ive got another white face echoplex and > have had a noise problem before, and last time i reseated the rams, roms > and the lil square chips and that solved it.........went to do that this > time and HORROR!!!!!! someones gone and put metal covers over the square > chips......so questions > 1.Any idead on the noise cause? > 2.
