Hi Folks,
I have (well, I think I have) beginner-intermediate-level electronics knowledge. I've built several guitar pedals and a tube guitar amp (under the watchful eye of my late-Father).
I have a general question - If I'm faced with a schematic that doesn't have a BOM, how do I determine the component characteristics? I'm primarily referring here to things like resistor wattage and also to capacitor voltage, but I'm also unclear about, say, when to use specific types of components such as metal film resistors, or the various types of capacitors.
Is there any online resource or textbook that discusses things like this?
As a simple example, I'm interested in building the Helios69 EQ which requires a make-up gain amp. I thought I'd try the TL072 version. How do I figure out the wattage/voltage ratings for the various components?
Cheers,
Chris
