Go to google and search "how to read capacitor values" you will find many links.
http://www.wikihow.com/Read-a-Capacitor This is just one, there are many...
uf 'u' is a multiplier, pf 'p' is a multiplier.... your 6pf cap usually will not have any
zero's. the 0.6pf would be wrong, and 6.0pf is usually not written. Anything
above 100 as in 600pf for example 6,000pf is usually not written as it cancels out
the 'p' multiplier.... (not really cancel, just not written) refer to the schematic
for voltage rating, as you stated, my schematic is a generic ctc-12 off the internet.
600v if ceramic is safe.... be careful about removing just one leg of ceramic caps in
a pc board, especially old ones, they are sometimes brittle, and not polarized,
so you don't have to worry about how to put them back....
On that page I referenced, down at the tips area, 6,000pf there is a convention
for writing values, possibly derived from scientific notation, or international
scientific standards for writing values. This is why you may or may not see a value
written in a specific way...
