[R-390] What's in the window?

[rbethman]

It is described in the wordy listing information.

"a compact HiFi speaker is included to go with the  *aftermarket 8 ohm 
audio stage* nestled in the space next to the PTO. (shown in the photos)."

I added the asterisks to try to highlight the specific portion.  
Apparently a solid state audio amplifier is mounted, (It appears to be 
on the chassis "wall" next to the PTO.), and this would be what that 
circuit board is.

Most likely it could be easily be removed and the diode load or the 
straight 600 ohm audio could be used.

Just IMHO.  Also worth about $0.02!
