Schematic typo???

[greenacarina]

I'm in the process of rounding up the bits to build a Superfuzz

and I notice that 2 of the resistors are labeled "1k8"
What does that translate to in english?
Thanks

1.8 kiloohms

The K or the M or the n or whatever sits where the decimal place is supposed to be.

I guess this convention came about because the little dot used to get obliterated either in the workshop (grease, wrinkling etc) or by repeated photocopying, with the result that the value was easily misread.

That will be "1.8k" .    It's just another way of labeling.  Capacitors values can be in this format as well, as in "4n7" instead of "4.7n"  .

EDIT: Beaten to it again!

Wonderful!! Thanks for the help!

I find it much much easier to see 1k8 or 4n7 than a bunch of "zero's" and decimal points BTW

I gather the convention of using the letter/range to parse the numbers arose because you could not always guarantee that the decimal point would be visible. 0.1uf could easily be misread as .01uf, so it is more reliable (especially when dealing with a low-res posting of a scan of a photocopy of a hand-drawn original) to indicate values with a big honking letter where the decimal might be.  Its a less ambiguous system, IMHO.

Incidentally, there have been several schematics over the years for the Superfuzz, indicating two different versions of the mid-scoop filter.  One has the 10k resistor, then the 22k one.  Another has the 22k first and 10k second.  The 10k should actually go first.  Placing the 22k first will situate the notch too far down in the spectrum.
