This is what's below the turntable. The big metal gubbins is the amplifier, and the two loudspeakers (yes, it has two of them) are partially revealed on the left- and right-hand sides of the cabinet. The amplifier will be removed, tested and repaired as necessary. You'll see more of this in the following photos. By the way, despite having two speakers this is a mono amplifier, not a stereo one.
