    I am a newbie to this site. Unable to track down replacement Zener diode 7m6, ZY15.

    Unsure of wattage, ampage or any other value so cannot find a replacement

    It is out of a Hughes and Kettner guitar amp

    My best guess is that it's a 2W 12V zener diode.

    Here is a link to some datasheets.

    See if the diode matches the physical specs in these datasheets.

    Steve, I think my guess is better: it's a 15V zener diode, see this datasheet.

    Of course it is. I googled for ZY12 didn't I!

    Looking at the datasheets I linked to would have revealed that too.

    In any case, I'd still confirm that the device is physically the same as what is in the datasheets (you wouldn't want to buy a replacement that didn't fit).
