    Unhappy High pitch sound and 60mA+ in mute amp 6 sneaky

    Hi!
    I soldered my amp 6 SNEAKY yesterday and everything looked okay.
    I cleaned the board with iso and set up my multimeter to measure current.
    Im using a 12v dc adapter to power the amp.

    Everything was okay when i powered it up, so I went ahead and closed the awake pins.
    When awake there is a high pitch sound comming from the amp(no speaker or input attached)
    The amp also draws around 60mA instead of the supposed 1mA.

    I'll post some high res pics in the afternoon.

    I'd really apreciate if someone could give me some hints as to what i've messed up.

    Cheers Niwai

    When you close the awake pin. You bring the amp out of sleep. The amp should draw 60mA when awake. Do not awake the amp without being loaded (attach speakers) and if you have no input you should ground the input (or attach an input).
