Could someone please verify I'm correct, or wrong with these?

I'm not well versed in this and don't want to blow anything up but I think I got this, this time. I hope.

Using this link:http://antiqueradio.org/art/recap13.jpg

I had to identify two molded paper cap values.

The first one has bands: RED, RED, ORN, GRAY, and BLU.
I read this as being a .00022uf 600v cap. Would that be correct?

The second has bands: YEL, PURP, RED, GREY and BLU.
I read this one as .0047uf 600v cap. Would this be correct?

Here's a pic of the first one, I cut it out the other day.

Thanks, for your help I really appreciate it! :banana:

The first one has bands: RED, RED, ORN, GRAY, and BLU.

0.022uf 600V. The values on those things are in picofarads, so it's 22 followed by three zeroes, for 22000pf. And the fourth band is black, not grey... that just shows 20% tolerance, which was pretty much standard on those things.

The second has bands: YEL, PURP, RED, GREY and BLU.

0.0047uf 600V. Or 4700pf, whichever you want to call it. Again, the fourth band is probably black...

OK thanks so much Nick the Nole! After I typed the .00022 I looked to see if I could find it on just radios cap chart and could not, so I wondered about the decimal.

Anyway, the more I do of this the better I'll get of course.

I'm more used to pinball and arcade game cap reading, pretty much only electrolytic type used there.

Thanks again!
