Hey there~! I normally don't like owning common gear that a lot of other musicians play, but I was thinking of looking into a 5150 or 6505 and hopefully modding it to my tastes

I just wanted to know if anyone here knows anywhere with instructions on different types of mods for 5150 or 6505 amps (I haven't chosen which yet) since I think it'll be fun to make a project out of it.
