Buying & Replacing Non Electrolics Caps

[skyeaudio]

I am New....When Replacing Non Electrolitic Caps is Capacitance of .01-600 the Same as .1 mfd 400vdc
ALSO this is an Old Magnatone 210 Where is the best Site to Buy New Caps for Older amps Like These Any thoughts?

NO...

1uF is 1000nF
.1uF is 100nF
.01uF is 10nF
.001uF is 1nF
And the voltage ratings speak for themselves.

Mouser Electronics, Digi Key, Jameco, MOJO Musical Supply, Antique Electronic Supply, Weber VST, New Sensor... the list is almost endless as they all sell pretty much the same components plus or minus some very cheap junk from China.

Here are a few sites to learn about capacitor values:

Thats awsome thanks....a Better Question may Be if a Cap is Listed .01-600 and thats all Does this always Mean uf or mfd even if its not Indicated?? the Good news is... I fixed the Amp Bad Solder from a Resisitor to Chasi Tapped it with a Sharpi =)

thanks Man!! your Page is Really Cool!! Another Question you may know...Blue Plasitic molded Caps...I know they are non Polerized....I'm guessing they are Tone Related.....01-600 markings...any tricks to Figuring out by looking What these Caps are made of...I can rule out Paper....(its tubler)... so its not Cerramic....its not an orange Drop....Does Color Indicate What a Cap may be made of?? your Site indicated Caps with uf Ratings would be made from Certain elements....Any Other thought....gota Start Somewhere thanks Again

Without a photo, its sounds like what you're describing maybe they are some sort of polyester or poly-metal film caps

First off, let us not confuse nf with mfd. Nf means nanofarad, which is 1000 picofarad - 1000pf. WHen you see mfd, that is not nanofarads, that is an older way of saying microfarad. On old drawings they would use mfd or even just mf to mean microfarad. We now use the uf. SOmetimes you see ufd, means same as uf. The "u" there is not really a u, it is a lower case Greek "mu." Since we don't have Greek letters on our keyboards, we use the English u which looks about the same. If you ever see the u looking kinda like script, then that is an actual mu symbol. For that matter, on older schematics they did not then use picofarads, they used micro-microfarads, and that was written as mmf. TV repair guys would refer to that as "mickey mouse," as in "I need a 270 mickeymouse disc ceramic." Those TV guys were clever, they were.

Yes, .01-600 (I myself tend to write it .01/600) will always mean .01uf At least on our stuff. COntext makes a difference. If you saw a filter cap marked 100/400, that would mean a 100uf 400 volt electrolytic. But if ti was in the tone stack wired to the treble control or maybe a brightness cap on a volume control, then it would mean 100pf. And then it would be a little disc ceramic of a silver-mica maybe.

Whatever it means, .01 something will never be the same thing as .1 something. Not on a guitar amp anyway.

Old paper caps WERE tubular. COlor does not tell you what it is made of, however if you recognize the orange caps as orange drops - a brand - you wuold then know they were film caps.
