POP at power off - A15MK2 & M15MK1

    Hi, MAD
    i have an issue with both my amps A15MK2 and M15MK1.
    The amps work fine with an amazing sound and i am very satisfied with them,
    but when i turn off the power switch or when i turn on the Standby switch for a pause, i got a strong POP from the speaker.
    Before to switch, I always turn to zero the volume of both channels of the amp, but i always got the POP. ;(
    I have a G3 Blues too, and it has not this issue, it is very quiet .

    can you help me to avoid this problem?

    Thanks in advance

    Hi,

    This could be capacitive discharge over the Output Stage,did you wait c.a 30 seconds after switch the Amp in Standby,before you switch Power off?,you had to go there cause the Capacitors take the Time to discharge.

    Also it could be tear off Spark in the Switches,but it seems to be unlikely,caus you had the Failure in 2 Amps.

    I think a discharge at difference Speed of the Capacitors in the Amp´s will be the most likely Cause.


    Best regards,
    Micha

    Thank you Micha,

    Does anyone else have the same problem?

    Thanks in advance
