To return to the 3130 which was the original subject of this thread, in 4 years I've no seen it again, so presumably it has continued to function properly. This being the case, I may fit 70 degree thermal trips on any NAD amplifier of this series-I have two in the W/S at the moment- and possibly on other amplifiers of similar design & construction. Might even think of adding, where practicable, o/p transistor emitter resistors of between 0.22 & 0.47 ohms each.
