caps in parallel?

Yeah, it's me again. If I need a .5mf cap can I use 2- .22mf and 1-.047mf in parallel for a total of .487mfs? Thanks, Brett

Are you using the caps in a low frequency circuit? Of so, you are OK to do so. If the circuit you are putting the caps in is at RF frequencies , you could affect your tuning, since the extra lead inductance may come into play.

Such as: at or above short wave frequencies.

Wow, you guy's are fast. It goes from the volume control to the chassis. If I'm reading this right that puts it in the 2nd detector.

There are usually only two caps that go off the vol control.

One couples the signal to the 1st Audio... and is anywhere from about .01 to .002uf

The other is RF by-pass and and may be 500pf to ground.

Are you doing this in a pinch or something? Three caps to replace one costs more, takes up more space and doesn't look that good (for what the cosmetics are worth). I hope you are planning on eventually using a .47 or something like that.
