that this was 25 years ago. Should have.
The production video switcher we used for many years, a Grass Valley Group
300-3A/B, used a grocery sack full of a slightly bigger than an airmail
stamp, custom made op-amp that Grass designed.
Of course, as the far end of the bathtub curve of time vs failure rates
approached, it lost a channel, one of those little ceramic cards had died.
I called Grass, they wanted $1500 and would not guarantee that the
remaining ones on the shelf were good. That wasn't good enough for me, so
I started scouring catalog's & calling the chip makers. I forget who came
to my rescue with a one rail 5 volt video speed op-amp with an in my hand
price of less that 2$. So I asked for samples & they sent 5, gratis.
I should have bought 50 because it was so much better and faster that it
threw the color phase noticeably off when that mixer channel was in use.
If I had sufficient stock, I would have shotgunned the other 5 identical
boards so they would have all matched again. But changing them out was a
good 3 hours a board, so it never got done, but by the time I retired, the
other 4 were in it because of more failures. Since one board then had 3 of
those in it, the color hue shift was getting to be obnoxiously obvious.
When I announced I was retiring, the first thing they did was replace it
because they knew I was the only one still living who might be able to fix
it. They paid about 100k for another brand new one from a new company, and
4 years later it was on its last legs.
Then digital needed to be done, so the building was rebuilt for a brand new
rack room and two control rooms, 3 more edit bays, 2 production offices,
and an all new area for engineering since there are now 2 tv channels, 4
programs, originating there plus a radio station. That has had its share
of 'teething' pains, but the junk seems to have largely been swept out in
the 5 years since, so its usually running pretty good. All with gigabit
ethernet, and some 10Gb in one instance, its nice to be able to move a 1
hour long program file from one box to another in 2 or 3 seconds. :)
