Ross Compressor (Help)

[Sdoro]

Hi everyone!
this is my frist time posting so i'm sorry if it's not belong here.

I'm building a Ross Compressor but i can't find a 0.05uF (503) capacitor and i was wondering if it can be replaced by a 0.047uF (473) capacitor or a serial union of a 0.047uF (473) and a 0.0033uF (332).

may be it work too with a serial union of a 0.047uF (473) and a 0.0022uF (222)

i'm really lost on this cause im not an electronic person so i will be thankful about this, also english it's not my first lenguge so sorry for every poorly worded sentence

Hi & Welcome..

Replace it with 47nF and walk in peace..

P.S.
A 47nF & a 3.3nF must be connected in parallel for an equivalent capacitance of 50.3nF..
(they work inversely of resistors..)

+1 what Antonis said. 47nF is close enough, don't worry about it. The tolerance on these part values is likely to be at least 10% (or even 20%), and 50nF versus 47nF is about 6%. In this position, the exact value is not critical at all, so it's not a problem.
