since I have been having hell finding a .056 cap I started looking for a possible sub and ran across this link and it has some good info regarding what you could substitute for your needed cap in terms of uf/mf, voltages, etc. enjoy :D

Also checked Mouser. http://ca.mouser.com/Passive-Components ... 92Z1z0z7l5

I would think all the usual suspects would have that value available.

most the times i have found that its not mandatory to have the exact same value,it depends on the position and function of the cap itself,also if you measure the exact value of a 47n cap many times its bigger than that,it could be 50/52,so its not much different from the above.
One more thing,being almost always first order filters in these circuits,to hear a difference by ear you have to double or halve the cap value,enough said.

I know the correct cap is available for sale at place the issue is they cost money that thing some of us americans still don't have thanks to useless politicians LOL, so I am looking towards old electronics to scavenge the parts from and the .056 hasn't turned up in any so I was looking for something else I can use ( like instead of a 1n914 diode I can use a 1n1418 ( to be more precise the 1n1418F which is what I have like 12 of so far and still have some in the last thng I disassembled and I have 3 or 8 more old 80s monitors in the attice that might also yield more 1n4148's LOL).

so as it stands I did find 1x .1uF/mF electrolytic cap but that's it for anything close next cap size close is a 1uF/mF which is bigger still ( kinda wondering if the 1uf would be better to use over the .1uf).

anyway the link I posted was just info regarding substitution where you can use a higher uf or higher voltage in place of what is speced in your schematics, I felt it might be helpful to others like myself that are rather noobish :P

See the E series of preferred numbers to understand the common values and why some are more common than others.
Learn about capacitors in series and in parallel to be able to "construct" other values from what you have available.
