This chassis was built for a short time. It was the last modular
RCA & last delta tube RCA. Saw very few of them. You will
need a manual & if you can find a training manual that would
be best.
It does have an interesting one try kick start. Also IIRC two ground systems,
One for power supply / HV and the other for the main chassis / tuners.
Good luck
