Got someone with a Kyocera receiver (R-851, 85 w/chan.) that they say

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:

I've seen many of those in different pro power amps.

It's a first for me. I can't say I've ever seen a kyocera amp in the US
either.

Do those heatpipes ever leak or break after being decades old?

Kyocera was sold by high end audio salons in the U.S., during the mid
80s, as an entry level line. The products were very well built and
reliable. One of their cd players was sold under the ADC brand name
at a very low price. It was probably the best cd player buy in its
day. Chuck
