Question about Audio Players & Recorders
NAD 3150 : amp runs fine but will randomly cut out (i.e. go silent), while all lights are still on (not protection light though). A slap or two (sometimes three) on the side of the unit makes it start working again. What is causing this problem / how can I fix it myself? Any info or links much appreciated!
Hello. Slapping and it working is a tail sign that there is a loose connection, bad solder point, loose wire. When a circuit board gets hot, solder joints separate and an opening occurs in the circuit. Open it up and get a visual. Look for cold solder joint, make sure all the connectors are secure. Good Luck

Since the problem seems to be sensitive to the volume level, I would be looking at the output wave form for any DC current. Although the protection circuit should detect any DC present, it is possible that some is leaking through. Also, verify that the speaker impedence is correct. If the amp is seeing too low an impedence load, it will work too hard causing excessive heat which will shutdown the unit as well.
Keep me posted.

The problem is in amplifier section caused by change value resistor or leak capacitor or cold ,loose or crack solder joint parts this the common problem of over heating and shuts out the amplifier caused by abnormal distribution of current,try to check all the capacitor and resistor and replaced the defected parts ,so your receivers works normal again.
Hope it may help you;

You are overloading your amp. IMO 640A cannot handle heavy loads.
Better change the speaker combo and connect something that puts right load on the 640A. Else, get a meaty amp from CA.
