Not that this surprises me, having seen how the British Defense Industry works on too many occasions
Yes, in moderation There's simply a point where the tools this type of older engineer prefers still make the job taking much longer than with a modern tool set operated by an engineer (older, younger, age doesn't really matter) who's learning and self-development hasn't stopped back in the '70s.
In the early '90s,the Tek or HP guys would come to our TV Studio to try to sell us their "latest & greatest " DSO.
They would uniformly fail at the first serious test,due to insufficient memory,an awkward UI,& a few other problems.
The group of people at these demonstrations ranged from Senior Engineers in their late '50s,down to young Techs who would have been in Kindergarten in the 1970s.
We were all favourably disposed towards Digital solutions to problems,as most Tech people of that time were.
Even the most enthusiastic supporter went away disappointed.
Most analog 'scopes around the Studio were Tek "400" series or later types,but we kept a couple ot 7603's around,which had a big advantage----you could use them with a 7L12 Spec Analyser plugin.
The last analog Tek 'scope we bought--can't remember the model,was a "lemon".
We kept sending it back,with no fix happening.
Tek would try to fob us off with a DSO instead--none of which could do the job.
Eventually,they found one that "just about" did it.
The only problem it had was aliasing between the sampling rate & the 4.433MHz colour subcarrier,when looking at a video signal at field rate,which looked like a much lower frequency signal superimposed on the display.
We could live with that,to have an instrument which didn't keep "croaking" on us!
Judging from this forum there are plenty small (one person band) companies who use older equipment to get the job done. I also noticed from visiting bigger companies that old equipment tends to stay for a long time.
Big companies often have big Equipment stores.
Older equipment may well linger for years.
It is also,often more cost effective to drag out an old 'scope to
use as the display for another seldom used specialised instrument,rather than hire the modern equivalent.
