I have however learned that electrolytic capacitors go dry so I don't pull them off unless they are rare value types. But as you would know they can be reformed with a HT power supply. These days I mainly pull off polyester caps, high power transistors and regulators with their heatsinks, transformers, some resistors and diodes with a decent amount of leg length and other oddball and useful components.
Hi Troy
Oh i never really had much trouble with caps apart from old valve radio ones they always had the odd one that played up .
Well i have a life time supply of electronic caps !
Every now and then i end up with heaps of old boards to scrap but its so easy these days just google the part your not sure about and you know what it is apart from those strange looking diodes might be a tunnel diode so many different types ...but if it has a number we are so lucky these days ...20 years ago you would of junked an ic with no way to know what it is .
The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.
