yamaha magicstomp

Hi everyone just before christmas my magicstomp sound went all distorted on any selected patch before eventually no sound at all , the unit powers up ok and the tuner works fine but no sound, if anyone can point me in the direction of someone who could repair it for me i would be very happy again.Regards Alan.

Step One: Check your output cables and clean the sockets.

Step Two: Try routing the output of the MagicStomp to a different destination (i.e. pedal or amp input).

Over the years I found that sometimes the power suply regulators for the +-15V (NJM7815FA and NJM7915FA) fail due to constant overheating. First the regulators deliver to low voltage (producing distortion) and after that giving no tone because the audio output gets muted, when the voltage is to low.

The service manuals (magicstomp as well as magicstomp II) are available at elektrotanya.com/showresult?what=yamaha%20ub99&kategoria=&kat2=all

Okay, I guess you also studied this thread than:

I never had this fault coming up with a distortion, but others reported it did (in an early state)...
