Hi everyone...

this is my first post on this forum :D

I just broke my power amp last week (cause of my foul). the power is big but the sound was crap for me. and then I trying to bread board the Marshall MG-30DFX power amp section.

it sounds best, kind of a 'flat' freq response. because it give me the same sound like my preamp output. (by the way Im using my own design preamp)
but the power is to weak, I thing it should be 30W come from my speaker (Im using 250W 8ohm speaker)
please help me guys, is that any way to make the power output more higer?

for the power supply Im have bipoar +/-25V with 3A CT transformer.
Thanks :D
