thanks for coming to help ill try tomorrow on taking off some of the capasitors that are too low and and measure their voltage and capacitance to see if they still seem weird
I apologise but I'm having trouble knowing if the +18 and -18 rails are correct as I'm not even sure if I'm measuring them off the right point when I measure off the v+ and ground as well as v- and ground the voltage is quite low but if I power the amp off and on again it seems to jump up then slowly decrease the voltage so I'm not sure what is happening but from another form I found people were saying to measure l11...

hey Im very new to repairing electronics with capacitors as well as using a multimeter so I need so help/guidance fixing this issue

recently I was handed a family members old NAD C320BEE that they had in their loft for storage for a few years but when powered on it went into power safety mode due to a problem on the protection circuit somewhere before it went into storage I was told it worked fine I found lots of people online talking about how the capasitors are known to be pretty bad in this model and can cause this issue the only problem being I don't have much experience sorting...
