 Amp keeps overheating - RattleandSmoke
My Cambridge 640a keeps over heating when using headphones, the circuit protection mode triggers but when I feel the top it is extremely hot. It always seems to happen when using headphones. It is worse with my Grado SR60is.

Anybody know what is causing this? There is no obvious problems with it :( I have an old Rotel pre amp so I may have to use that to drive these headphones or buy a headphone amp :(

The thing is amp used to work perfectly with this headphones so I am not sure what is up.
