Cannot see anything physically wrong with either C25 or R34 so will get and fit replacements to test.
I have checked the HP socket- seems ok, no dry joints, good continuity. But I was checking it with my HP adaptor (small jack to large) and I remembered that this adaptor is a bit suspect. Could it be that a intermittent headphone connection could cause the amp to blow (I was using this adaptor on both occasions)?
There was no inslating mica on the chip when I removed it so I didn't put any in on the replacement. Is that going to cause a problem? ...I meant to say about that the expensive thermal grease would stop it overheating on its own sorry about confusion, but didn't consider electrical conductivity... however the second time I used standard thermal grease for the replacement and it still blew (after only a couple of minutes). Interestingly both times it blew only after switching off and back on.
About the "maybe the guy who sold it to me knew something" thing... I was just ranting in anger... you're right Enzo noone could know when something is going to fail... unless of course it had failed before and he hadn't mentioned this concern to me.
