First of all I have very little experience building amps, though I have successfully built a few pedal kits. I was just kicking around the seemingly simple idea of building my own coliseum slave/slaves(ahhahhahhaahh) to add to my rig or have as backups in case i have to service one at the time of a gig. I own one and think it would be easy seeing the innards cosisting of very very few parts I regularly vac out the heads and clean the pots(though theres only one in the model i'm speaking of(coliseum slave)... I assume the parts/components are difficult to get ahold of... as i said before I'm a beginner but i am firm as far as only wanting the sunn solid state sound replicated by my hands, no matter what the cost.... i just want the satisfaction of saying that is not just a any ss power amp slave, that is a replica of a sunn coliseum slave that i built... I would also like to move on from this initial undertaking to build the coliseum bass and coliseum lead heads that are nearing an impossibility to find... any suggestions/help??? HELPPPPPPPPPPP!!!!!!!!!
