Default Kenwood KR-A57R receiver: worth messing with?

I was given this unit in non-working condition. Powers on, front panel
display works perfectly, appears to tune in stations correctly. Plus the
power supply appears to be working correctly: at least I measured
voltage at the output transistors. But nothing but silence from the
speaker outputs. The speaker relay clicks when the impedance-selection
switch is moved.

The boards are very dusty and covered with lint. Other than this,
everything appears to be as it should be.

Any advice for working on this receiver? Is it even worth messing with?
If not, next step is cannibalization.
