Greetings, I have a Vox AC4tv amp. This is the one that everybody warns about opening up and working on because of something to do with the chassis design (I think) and how it can hold dangerously high voltages even when unplugged. So I just ordered a pair of new tubes and this will be my first ever tube swap. They should arrive in the next few days. Yesterday morning I unplugged my amp and it is now just sitting on its own, no cables or anything plugged into it. If I just let it sit like that for a few days will that create a safe situation for me to take it apart and get in there? Or is there something more to it that I am unaware of?
