Bumble bee value?
Working on the formerly live-mouse-infested Magnavox, and there's only one bumblebee in it. Just so I don't screw this up
 , can anyone help me out with the value of this cap? TIA

looks like .047 but im unsure of the color of the 4th band is blue or gray, if you have 600 v i would use it depending on what circuit its in.

The ones with cash value are .022 @ 400V. Here's a pair of used ones for $75:

Two more of these, guys, if you would. These are on the Zenith Custom 23 Super H Chassis. I just don't trust my eyes, and I don't have a schematic handy

I like to use a conversion chart such as this: http://antiqueradio.org/art/recap13.jpg
I have a better one printed out, but can't remember where I found it on the net. If you can read resistor color code, the capacitance is the resistor color code of those 'K' numbers on modern yellow replacements. For example a bumble bee with the first three bands YEL PUR ORG decodes to 473 which can be replaced by a modern cap with value of 473K(this is 47*10^3 thousand pico farads or .047uF)

Still a bit confusing for me. How do you get the voltage rating?
One more, gentlemen, if you don't mind

Quote:
If it's Brown, Black, Yellow it would be .1, the Blue stripe at the end would make it 600 volts. The last stripe is the voltage and it's the same color code, Brown=100v, red=200v, yellow=400v, Blue=600v. Not sure what that 4th band is, possibly tolerance?

Here's a link to a chart for BB Caps. 4th band is tolerance, Black is 20%, probably don't have to worry tolerance unless it's a green stripe, that's 5%, white is 10% and most modern caps are probably going to be within that.

I agree with 0.1uF/600v for that last one.
