I'm new to the DIY vacuum tube world, and (as I'm a guitarist) I want to make my first step building amps.
I know some electronics basic principles (I've done it in high school) so I know what is a potentiometer, an high-pass filter and so on (Kirchoff rules, and blabla), but a lot of time has passed since I was actively looking into these things.
Do you recommend any book to start? As example, I looked into the Mike Romberg's scheme of Cerberus (you can find it in the Marshall section) but I don't know, for instance, the purpose of the resistor cross ( 1M - 1M with 470 and 10K) in the power section.
As the first time, I'm planning to buy the Madamp M15Mk1 kit and start to do some soldering
Thank you for any hints.
