which design that you're using? irs900 or amplificador 1200?

if this if your first project, it would be best if you could try with a lower, say 35 or 45v first before moving to >50v. my amp which is dead stable at 35v went up in smoke when i feed it 65v. make a stable amp at lower voltage first before going higher.
