Total agree there as it's just nuts wasting lots of money to build it. I mean if that thing goes wrong bang flash pop you get a big pile of burnt parts!!

This is in relation to the circuit of the 1000w amp pointed out at the start..

what this amp needs is a good SOA protection circuit...use a series lamp tester, it saves a lot of grief..
