I ordered a JJ ECC83-S today for my Laney combo. I need some advice on how to install it, so i don't kill myself poking around in my 120 watt amp. Is this simply a plug and play type of situation, or is soldering required? What dangers are present, and how do i protect myself against them? What is biasing, how do i know if i need to do this, and how do i do it? Any wisdom would be greatly appreciated.
