['LIVEWIRE?']

I have now seen both the American and British 'How TVs were made' You Tube videos and, as expected, the processes shown in the two are broadly similar, since both were dealing with the Mass Production of black & White sets of the same era, and which, broadly speaking would surely have been similar in design, aside from the obvious differences in the TV broadcast standards, and the mains voltage/frequency difference. Incidentally I'm assuming that U.S. TVs were basically 'live chassis' sets, as ours were.
