if resistors get out of tolerance. don't that mean that it would when it's in use. then over time it would do the same thing thus damaging the component ?
i have done some electronic projects. and i never even thought about this ....
@TheTarrMan, Most of the time you must remove one side from the circuit.
The exception would be lets say the resistor had a capacitor on one end oe that end is connected to a grid or other tube element you do not have to remove it.
On transistor stuff you most always have to remove one side of the resistor.
Hi Bill, Thanks for another great video. I'm still discovering how many of these educational and fun videos you have created. I sure hope you can rebuild your electronics workshop again even if it doesn't have all that 'good stuff' you previously had. I have compelling evidence that 'old timers' that have their 'cave' workshops live much longer than young bucks that don't. :-)
I've heard that many old resistors gain in moisture. Because of that, it was suggested that putting them in gas oven over just the pilot light helps to bring them closer to tolerance. I've never tried it, the cost of gas vs the price of new resistors......
A few years ago, I came by a large lot of NOS carbon composition resistors in 1/8W, 1/4W, 1/2W, 1W and 2W sizes. I checked them all and found the smaller the physical size (lower wattage), the more likely the part was to be out of tolerance (always high value).
Thumbs up,sir...I learned something new!!!! I love electronics! Thanks for sharing...u rock! Mbc

is there a different type of resistor that won't go bad? if not how would you get around the problem?

@MrOne2watch Carbon film or wire wound.

@MrOne2watch I would say yes thay could, for that reason I would not use them, although I myself have.
But thinking back on it I should not have used them if they drifted out of tolerance..

can you check the resistors when there still in the board, or do you need to take them out? Is there a good way to check a board for bad resistors?

Hi Phonojack, Thank You very much.
I don't think I will be setting up a shop right away, I hope to be able to someday.
Thanks for watching.

Hi, Well that is a new one on me, but resistors taking on moture would lower the resistance.
Yes the cost of gas vs the price of resistors....Hee Hee
Thanks for stopping by.
