when i apply remote voltage the amp will constantly turn on and off (drawing current) i'm assuming that's the protection making it turn on and off. so i opened it a noticed the 2 filter caps (C26,C27) were bubbled out, i don't think they actually vented but i replaced them anyway. the amp still did the same thing (on/off) so i checked the rectifiers and found one bad (D9)(not shorted but the resistance check was out of tollerance). while i had the rectifiers out i powered up the amp with no problem (perfect square wave & virtually no current draw). so i replaced the bad one and reinstalleed the good one. but when i attempted to power up the amp it did the exact same thing (on/off). non of the outputs are shorted but i did notice that the Q410 & Q411 outputs were getting hotter than any of the other outputs. i removed them from the circuit and they checked out okay. while they were out i attempted to power up the amp with the same results (on/off). so i reinstalled them and removed their drivers (Q408 & Q409), they checked out okay. so i tried to power up the amp with them out and now the amp will stay on but is still drawing current.
I'm not sure where i should look next.
