   Does the receiver have connections for two sets of speakers? Is
there a speaker selector rotary dial on front (often ntegrated with a
power switch) or two pushbuttons that select speaker A or speaker B or
both? It's likely set on both, which likely put the speakers in
series, making two 8 ohm speakers into a 16 ohm load, vs. putting them
in parallel which would make a 4 ohm load.

   It might start sounding funny if the output transistors start
