    Question O3 HHCH Disass

    Anyone have any tips on the disassembly procedure for the o3 head?

    I think it might be glued, however, I'm hoping there's a way to split it by manipulating the mic hangup in some manner.

    I have one that will not power up, and has the terrible rattle sound of a loose part inside when shaken


    Any help at all would be much appreciated.

    Thanks!

    Did you look at the service manual(s)?

    I didn't see anything about the o3 mentioned in the basic or detailed XTL5 service manual...unless there's another manual it might be in?

    Well, with no patience, and a screwdriver, I found it.

    There's two very small plastic clips in the connector housing at the bottom that need to be pried outward.

    The housing will then split into two pieces.

    Thankfully, it just looks like the flex simply disconnected.

    Guess I spoke too soon - Looks like some of the solder joints failed, and the rattling was a couple transistors rolling around under some type of shielding or heatsink.

    Not in my MOL catlogue...anyone have a source for these, or am I on the wonderful path of a depot flat rate repair?
