Can someone give me a step by step guide on how to change tubes in my jmd 1 100 if i want the same kind of tubes AND if i want others tubes.
I've watched some videos but i'm still not sure.

You'll need to bias your amp if you change your power tubes, that can get both dangerous if you don't know how to do it.
Preamp tubes can be changed easily (not sure how much effect it will have because your amp has digitalness...)
Most Marshall amps run el34s, but its also capable to run kt88/66 and many others,
Another thing people say is to buy matched tubes, I beg to differ
If your output tubes can be biased individually I recommend trying a mix of different tubes. It really makes the amp sound individual and the sound much more unique (in a good way)
THIS IS ONE FANTASTIC POST

HAHA, YOU LOOKED
