A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

Hi everyone,
this is my first post even though I have been around for a long time. I decided to jump on the valve building train and build a stereo version of Fred Nachbaur's MiniBlok II.
I have been reading about designing and constructing valve circuits but it is not clear to me what type of resistors and capacitors to use.
My understanding so far is:
metal film resistors are the ones with the least hum/noise.
use electrolytic capacitors for the power supply and cathode bypass capacitors. Are there some particular kind/brand/characteristics of electrolytic caps I should look for?
use some other kind (polypropylene?) for coupling capasitors, etc.
I would really appreciate it if someone could explain to me in plain english what I should use and when/where.
