Newest acquisition - a 37-670B
#5

That looks like a nice little girl cat, like many cats do she seems to be investigating what's going on. I'm just taking a guess here but I'm sure that the plug and two switches are some sort of phonograph input, or at least an input to the audio amp, either that or someone was stealing power from the power supply to operate some sort of accessory like an external BFO unit.
Regards
Arran
