Bean counters are often not smart with those decisions. Many don't seem 
to understand that donating equipment would net the company a nice big 
tax deduction. Even if they'd just call in the guys from the next tech 
bone yard they'd at least get a small amount per pound of weight. Plus 
lower charges from the waste disposal service.

Even my over 40 year old first oscilloscope still has a job. Not here 
but in a high school I donated it to. I didn't need a tax receipt, just 
wanted to make sure the kids have something that makes them literally 
see waveform changes as they create them.

Really smart managers in high-tech companies maek sure there is a junk 
room where old gear is kept instead of tossed. Over my career that has 
saved the bacon many times. Occasionally I had to invest an hour or two 
of billed time but then the rejuvenated old analog scope diagnosed the 
problem they had been chasing for days.

Old rejuvenation trick when in a hurry: Find all trimpots, then go one 
by one. Place a pointer such as a compass or a long sowing needle onto 
its body to mark the wiper position, turn the wiper peg to peg several 
times, then back to where it was. More hardcore are the boxes from the 
80's and 90's where their design engineers though that tantalum caps 
were a good idea. That's a lot of work and only makes sense if you 
really, really want that piece of equipment. Even worse is when that 
dreaded #@&*!! plastic rod for the delayed trigger goes chingalingaling 
in a Tek 2465 and you really need such a fast analog scope (happened 
several times). That's almost like trying to change the clutch in a 
Citroen DS21.

That Tek 2465 is so good that if I'd started my consulting biz today I'd 
immediately look for 2-3 of them. There is nothing that could ever 
replace these.
