poly capaciotrs

Hi,and thanks for letting me join.I am pretty new to electronics, but have always 'fiddled' with them over the years, but now i am learning how things work officialy.I have started to re cap some old NAD amplifiers and i am finding it hard to source some of them.So my question is as an example i cant find a poly cap 8200pf(8.2nf) 50v +/-5%, the closest i can find is is either a 6.8nf or 10nf at the same voltage and a tolerence of +/-10%.I guess if i try and look even harder i could find the exact ones, but i dont want to try too many places i dont know about and wouldn't trust.Im trying to stick to good makes such as panasonic, nichicon etc so iguess what i need to know is can you use the higher or lower value and what the effects would be using either, many thanks

Have you tried Mouser or Digikey or any reliable distributor? Specify that you look for a film cap, with the 8200nF and apply the filters. I have ore than 100 selections from VIshay alone, at Mouser.ca. You can use a voltage higher or equal to the one that you chose, generally without any problem (except for the price). The only disavantage, is that if you buy just one, the transport will cost much, much, more than the component itself. A second alternative is to buy 5 of them at Ebay or Banggood or AliExpress, if you are ready to test them yourself, one by one.
