Perry is correct as always, and I have seen these coils go south more then once. Jaime even sells the cores so replacements can be made. So check the black mark well as it sounds like you may have a intermittent problem there...

..so if one or more inductors were shorted could this cause the PS to go a bit crazy?

If the winding shorted to the case or to another component, it could have caused excessive current draw. With four individual inductors shorts between the windings of an individual inductor won't cause excessive current draw.

OK, disconnected the inductors and still have problems.. with just 2 good fets installed (one on either side of caps) the amp starts to draw about .5amp and steadily rises to over 6amps before I pull power, one side seams a lot hotter than the other?

one other thing I have noticed is when just remote and earth are connected one of the thermal switches gets very hot (occasionally, not always), not sure if this is anything to do with me bypassing this (remember I had previous issues?).

damn this amp has been nothing but trouble from the offset

Did you check or replace the PNP driver transistors and the gate resistors?

Are you sure that you have a good connection between the gate resistor and the gate leg of the FET?

I did replace one driver (a1562) last time round and have 1 spare left, gate resistors check out OK and will recheck the connections of the 2 fets fitted..

this is giving me lot of headache right now, been through the PS checking solder connections and it's now pulling 16 amps straight away and the fet on the right gets too hot to touch instantly, the one on the left is fine I have replaced A1562 again just in case and also the silver/round component just under it. all resistors appear to be fine on both sides of cap bank.

it's strange how at 1st the amp was just pulling 0.3amp (which steadily climbed and climbed to over 8amp), and since going over all solder connections it now just rockets up to 16 amp straight away

got this nailed, I had a bad solder on the A1562 so no connection to the gate resistors..

strange how you can put an amp to one side for a while, then come back and figure it out straight away!

now I need 8 new PS fets as one was shorted..
