well pulled the board out the amp to gain access to the caps and to drill out the rounded bolt in the heat sink

and guess what !!

one of the thermal resistors dropped out the board its never been soldered in its just had the bolt holding it lol!!

oh what does the sticker under the power terminals relate too guys??

maybe the solder evaporated with heat!!

while it's out it's worth checking the clip lights are working on the middle of the board, no biggie but the circuit can fail and it's an easy fix

cool tell me more just the leds that fail???

and theres no solder on the pads at all the other side is soldered in also no remnants on the legs so looks like it was missed from new!

I suspect in it's history someone over tightened the locating screw and wrenched it out!

it's not the actual led's that fail but a small transistor..

the amp has clip lights on the end plate but it's the ones in the middle of the board that go, one of mine has an led out, never bothered me but will fix it when i do the caps at some point.
