No problem at all Spooney. When people tell me they see 1 or 2 blown fets or outputs I dont replace just 1 or 2 i replace them all with brand new . All of the date codes have to match so the amp is reliable. Every amp that comes in my door i go through the amp 100% before i apply any power to it. Ive seen a few come in that they say 1 fet is burnt and it ends up being all the fets and outputs that need to be replaced. Heres a fact out of 20 amps that came in for repair only 3 of them had defective power supply fets and nothing else was wrong. The other amps needed more work then just fets like outputs,drivers,gate resistors,ect. So i know what your saying.
