I use my spell shaker

For other 'tronics, when going back in time, sixties seventies when working in the teefee studios
I had to keep a zillion pieces of interconnected equipment running often with a very short time to fix things or work around the problem,
as 'the show must go on', and as it was the national network no black screen or 'sorry' allowed.
Having a studio full of contracted artists waiting for an hour is a no no too.
From film to videotape to all sort of cameras, synchronization, Eurovision network, management, fault finding
what not
Having had to repair (and to do that get into depth of all that stuff) often within minutes makes you aware of so many different designs by
so many different companies that it widens the spectrum of your neural net...
Later I also had my own teefee repair shop... Then after that went to design stuff for all sort of things
Bit different from being stuck in one thing, also you learn what counts
But you need to know the basics, not only of the components, but also of the systems, the organization,
who has the power,,, What to do in emergencies with hundreds of people on the set.. Public too sometimes.
And we had the famous red phone from the government that would / could ring and special procedures were to be followed
some stored in a safe, national emergency, unite the several channels, did head control room for a while too, not just 'tronics.
Fun, some could not handle it, seen them go,

to pea in the sea .. it may help some here who only can commie-nukate in one language  to at least do some self-inspection
or flex their brain's language center a bit .

Yea geny -us ?
