Got someone with a Kyocera receiver (R-851, 85 w/chan.) that they say
"smells like something's burning". Don't have more specific information
than that; I'm assuming no magic smoke is visible. I'm advising them
that perhaps something (dust, etc.) is in the heat sink that's getting
heated and smelling. Apparently the output stages (MOSFET) of these
beasts tend to run on the hot side.

weird heatsink in that thing:

**Ah, heat pipes. Quite common in the late 1970s, early 1980s. If the fluid
has leaked, there can be problems. A quick way to test is to power up and
ensure that heat travels rapidly (less than 10 seconds) from the hot devices
to the other end of the heat pipe. If it doesn't then it is possible that
the fluid is gone from inside the pipe.
