    Hi guys,
    I'm new on this forum. I do electronic project not enough often.I believe what I want to ask is easy, but for me!!!!!!!!!
    I have a Brother Ptouch 1290 that use 6 batteries AAA = 9volts. Brother sell an electric adapter for close of $25.00. I'm sure that I can made it myself (but with your help).

    When I put a 9 volts adapter in the socket I have .87 volts at the load of Ptouch(capacitor 3300 uF. Where the voltage are gone.

    On the plan I write a Zener Diode but not sure if it is.

    The adapter 9 volts without load have close of 13.5 volts. It's written 9 volts on. When I put a 9 volts adapter nothing happen.
