I'll mention to you that I picked up a model 19LZX at Kutzstown in the spring. Nice set and I got it from an old friend that I haven't seen in over 20yrs. It's working but hasn't been serviced other than replacing the caps in the p/s which was done before I got it.
The hole in the back of the chassis may have been for round AC connector which was used on the LZX model. The power to that connector is switch by the switch on the volume control.
