Worth saving?
« on: September 18, 2015, 11:11:56 pm »
Hello:

Where i work there are lots of things i think are treasures being thrown in the trash. Old tek stuff, like instruments and tek branded chips/components. I try to save the ones i think are noteworthy, but can't save everything.
Today i found this set of resistors, i measured them with a normal multimeter and they were fine, i'll read them with a proper >6 digits mm tomorrow or next week.
I have a weak spot for metrology, but this things are big!
Can they really be replaced by something modern? maybe use this as reference against some zfoil resistor, and keep that as reference? I'm also not very fond of putting them on the'bay.

Big question: are they worth saving? I need to buy them from my workplace at some random price or for about 1€ per kilo.

Best Regards

Welcome to the forum.

Certainly yes, save them.

There is a For Sale section on this forum.   You could ask for asking prices there.

Save them, sell them on the forum if you feel you need to.

I was just looking at reels of manganin in order to roll my own resistors.  :-+ Definitely worth saving.

I just bought a similar one to one of those for a hundred bucks or so on ebay, because it looked cool and I was drunk. It's also how I ended up with a working VIC-20, a collection of old broken keithley meters, a rotary slide rule from russia (looks like a pocket watch, kind of neat.) and a cube of pure tungsten. (heavy.)

The moral, don't drink and ebay if you have a thing for vintage electronics.

the cube of pure tungsten seems kind of random in that selection

It's pretty neat, twice as dense as lead, fun to hand it to someone and watch them do a double take when they heft it. Also makes all those movies where people are robbing banks and tossing and carrying around gold bars look pretty implausible when you realize how heavy those bars would actually be. (gold and tungsten are about the same density, a bit more than uranium).

I just need to find an exact match made of magnesium (which looks identical in its metalic form but is incredibly light) to mess with people.

At a 1€ a kg worth getting. Even if they are bad, they look cool.

No way, don't educate people around about good deals, or prices for good stuff will quickly skyrocket   :-/O. Camp your deals undercover  :blah:

Take the tungsten bar and coat with gold, then it will be a gold bar.

Xteve,

If I had the chance to buy those resistors for 1 Eur/Kg, I wouldn’t think twice…
The same with Tek instruments and components – Even if you don’t need them, you can always sell and make some money.  :)
