circuit modifications in amps

[usernamename]

I want to mod an amp (toobs!). But I dont know what I'm doing and dont feel like taking an EE course.

I'm not touching the power amp, only the pre-amp.
I know not to touch things while the amp is on without covers (High voltage)
Is it safe to add/remove resistors and capacitors at random and not damage anything. Or are there rules to follow?
Antying else I should know to stop the deadly sound of sudden silence?

If you're trying to remove resistors and capacitors at random, you're going to run into some problems. There are of course rules to follow.

Some weirdo made a post a while ago with an introduction to tube preamp design, that may have some useful information for you. But perhaps if you could let us know what it is you're trying to accomplish, someone may be able to point you in the right direction.

Sounds like you want to circuit bend, but without any true aim as to what you want to achieve?

I'd at least source a schematic so you can tell which component belongs to which part of the circuit (eq, drive, volume, etc...) so you can swap caps to change filtering or the things that cause clipping.
