The C stands for Reverse Log Taper, so you need a 1M Reverse Log Taper

General Questions / Re: Electrolytic Capacitor type depending on usage

Really amazing information, thanks!
Based on the information here I think I'll go for what I initially thought - Low Impedance ones for the capacitors that do power supply filtering and audio grade ones for the signal application.
Indeed the price difference isn't THAT different...

Well I can imagine they're trying to sell off some more expensive stuff.
Though just to satisfy my curiosity, here are 4 similar capacitors. Their purpose, according to Mouser, is different though:
Low Impedance
Bi-Polar/Non-Polar
Audio Grade
General Purpose
The Low Impedance one does have a higher ripple current. Between the other ones I can't really say what's the big difference. Whether it makes a difference in sound/noise...
Could be interesting to go for those Low-Impedance ones for the power supply filtering caps...
In-between, are the cap number distinctions (PS filtering / signal path) I mentioned in my first post correct?

General Questions / Electrolytic Capacitor type depending on usage
October 23, 2012, 05:16:10 PM
Now that I have a basic grasp on resistors (thanks for the help!) I've been reading up on capacitors.
Am I correct in saying that for the electrolytic ones, one needs to see whether it's used in the signal path or the current path?
For the former, that would mean going for 'Audio grade' ones, for the latter you'd buy the ones with a high ripple current value (does these types have a purpose name as well?)
So for the Current Lover that would mean C6, C16, C17, C20 and C21 would be for power supply filtering, and C14, C15 and C24 for the signal (so audio grade)?
For the Road Rage they would all be for power supply filtering, except for C5 and C6.

Has to do with Ohms law it seems. I seem to recall this from my Physics courses from way back 
Thanks for the confirmation!

General Questions / Power Rating
October 19, 2012, 07:33:33 PM
Hi guys,
I have a Current Lover and Road Rage PCB on the way, which will be my first build where I'll actually have to gather all components myself.
Seeing as I only have a limited knowledge about the electronics, I'm a bit confused about the Power Rating of resistors.
From what I read, buying resistors with 1/4W should be OK for most applications.
With that in mind, I also gathered that RN55's are really great resistors, but they seem to come with 1/8W power rating.
So how do I determine how much I'll actually need for a given circuit?
