M1.5 ticking noise

Post by lanf08 » Thu Mar 04, 2010 9:28 am

Hi have a M1.5 that is making ticking noise. The noise is coming from the power supply and is doing a tick, tick non stop at a relatively fast speed. Can anyone help me on that....

Get in there and check the supply (rail) voltage. It sounds like it's too high. There is a pot in there to do this. I got an M-500 to work on that made that sound, and when I turned it down, it stopped.
It should sound like it isn't there!
