A Panasonic SA AXK72 did not show up in the Manual Library of HiFiEngine.com.
A web search did not list such a model.

Consider . . . . .Panasonic SA-AKX72PH . . . .instead.

Well, HiFiEngine shows a Panasonic SA-AKX[17,18,32,36,52]
One of those might be close enough to get started...

[edit]
Oh look! A web search turns up this!
