I just repaired a crossover and during test I used those kind of crocodile clips... The contact was so bad the frequency varies between reconnections.
Sorry but I disagree. Capxon capacitors, besides the capacitors plague, are constantly associated with failing devices. They were exploding two years ago, they were in the Samsung tvc, they are in Behringer products with high fail rate, they are in failing SMPS. They are all over the internet and from a customer standpoint I would not buy a device with CapXon capacitors inside, ever.
That name reminds me of a phrase that starts with fu and ends with you.Fuhjjyuu
Good ones will have ageing parameters specified in the data sheet.Is there a source for information on which manufacturer makes caps and resistors that are the “best” as in “at or close to ratings and stay that way for a long time” ?
Unless one is an avid DIYer it’s very hard to know what to buy.

Note that this is only my personal opinion and I fully support the statements from carlob and mansr.
As far as resistors go: Panasonic, Susumu, Vishay and TE Conn. are probably 3 of the most popular and reputable manufacturers and they all usually have extensive datasheets. In my projects I use lots of MELF MMA0204 from Vishay as well as Susumu RG-Series or Panasonic ERA-Series 0805 precision resistors. For through-hole mainly MBB0207 from Vishay. It also depends on availability and price a lot. For example in the EU, Panasonic ERA-Series are fairly affordable (for 0,1%-precision resistors) on TME.eu as long as you buy 100+ per value, so that's why I use those a lot. For non-precision resistors, I stick to reputable brands and go by price mainly.

Bateman’s articles are interesting, but one must be careful to understand the areas of validity for the sorts of measurements he presents.For those interested in possibly learning something, look up the work of Cyril Bateman.
