RE: used edp - strange humming

["Andy Ewen " <andy.ewen@btinternet.com>]

Yup, they all have this mechanical hum to a degree and it's just the
laminations in the mains transformer vibrating. I've never had a unit
fail due to the mains transformer so it is nothing to worry about. Most
units have some foam tape on the top of the transformer so it gets
'sandwiched' by the lid and reduces the vibration to a level that is not
noticed. Some earlier units did not have the foam tape fitted. You can
quite easily fit this yourself with some suitable sticky-backed foam
about 2-3mm thick.

Hope this puts your mind at ease; go buy this bargain EDP!

Subject: used edp - strange humming

Hi folks,

An aquaitance of mine happened to have a an edp just sitting around 
which was rescued from a tech disposal at the music store he works at 
(yes, it was going to be thrown out!).  Thing is, he is prepared to sell

it to me at a potentially unbeatable price. 

Are there any caveats to look for when buying a used edp.  Its maxed out

in memory already,  has no footpedal, but appears to be working 
perfectly except for a loud electromechanical sounding humming coming 
from the lid near the power supply.  It only hums when the lid is on the

unit however - without the lid it seems like a perfectly operational 
edp.  Anybody out there have any ideas what this humming might be?  Do 
all edps hum like this?  I wouldn't want to buy the unit and have it die

on me straight away, as getting it fixed here in Australia might not be 
the easiest thing.

thanks in advance for any replies,

Michael Noble
