Hey guys , Thanks for info on the last post . But I have another question . I was looking at bean's most used cap list . I'm guessing he uses some sort of short hand for writing values , like an " x " between the values as in , 47x1 or 100x3 etc. Whats the "x" mean ? I also have seen 100R and 2k2 or 2M2 . Is there a lnfo list of the type of lettering so I know what values I'm supposed get ? I'm trying to figure this stuff out . Thanks Dave P.S. STOP LAUGHING YOU GUYS !!!! ( just kidding )
It's just being used as a multiplier. For instance say you're ordering in quantities of 10.
100k x 3 would be 30 resistors
1M x 1 would be 10 resistors
4.8k x 4 would be 40 resistors

The k, M, R, and n indicate the multiplier. It's more common in European notation, but it's a good way of never missing the decimal point.
K = kilo
M= Meg
R = no multiplier
n= nano
And if the multiplier is inside the numerals, it represents a decimal point.
i.e. 4K7 is 4.7K ohms, 2n2 is 2.2nF, etc.
So if the electrolytic cap value 100x3 , It means 100uf times 3 which would be 100uf @ 30 pcs . Is this correct ? Thanks D
It partly goes back to photocopiers. The more generations a copy was from the original schematic, the worse the chance that the decimal point in, say, 4.8k would be lost (or perceived as flyshit), and someone would whack in a 48k resistor. Whereas putting 4k8 makes it very obviously NOT a photocopy error.
I understand what your saying about the 4k8 as being 4.8k . But here's what I'm talking about check this thread toward the bottom http://www.madbeanpedals.com/forum/index.php?topic=66.0
Now on beans list for Ceramic and Electrolytic cap ordering it says 47x1 . So dose that mean 47x1 = 47pf times 10 and the 10 meaning 10 pcs and for Electrolytic 1x3 = 1uf times 3= 30 pcs ? Help please Dave
My post above already answered the question. ???
The x is a multiplier for quantity in that linked post.

Thank you Josh , I appreciate your patience . D
No problem! Ask away ;D
