Disassembling PB "silver saucer" power adapter?

[jen729w]

Hi there.

I have a PB G3 with the "silver saucer" power adapter. While it still works, I'm noticing that the connection where the cloverleaf shape dooby coming from my wall socket joins the saucer itself is getting a bit temperamental. It takes a bit of a wiggle before it'll decide to supply power.

I'm sure this is just internal wiring coming slightly loose, but I'll be buggered if I can work out how to get the main saucer unit apart. I don't want to just try brute force - knowing my luck, I'll end up breaking something that, currently, works.

Any ideas, anybody? (It's part number M7332, just so we're absolutely sure what we're on about.)

Thanks, :-)
