Title: Capacitor help
Post by: den1976 on December 12, 2012, 11:33:12 am

 :w2: I need help finding some DC voltage caps or can I replace them with ac voltage orange drops. I have an RCA MI38104A that has dc voltage caps in it some are on the pots some are on the tube pins.They are clearly marked with the negative and positive sides and with voltages of 600,400,&200 MFD's are .47,.1,.001,.047,.22,&.033. I can't seem to find any below the .47 one anywhere. If I can't find them can I use the orange drops in place of them? Thanks for the help.

All capacitors are DC voltage.You can use the equivalent ratings of orange drops for any of those caps.

Yes, you're looking for a film cap, not an electrolytic. The black stripe on the originals indicated the outer foil, which is sometimes marked on modern caps (but very often not).
