MY QUESTION IS THIS:
Would failed power supply caps cause peripheral damage to the amp, preamp or control circuits ? Supposedly there is "protection" for "DC offset, over current and over heat"

I have a Proton AM-656 amplifier with "Dynamic Power on Demand" which is a second higher voltage supply rail (switched to when needed) that creates 6db of headroom and 2 ohm stable. I did not think there was fault protection, turns out the schematic block diagram states there is.

One day with the amp power on I tightened/snugged up the speaker binding post. There was a single frayed speaker wire (unnoticed) that shorted. The amp proceed to billow smoke. I looked inside to find several power supply caps having oozed their electrolyte onto the circuit board. 

I am shopping to recap two of my other amps and was thinking of recapping the Proton, however I do not want to waste my time if there is likely to be damage to the circuits other than electrolytic capacitors.


Question: CSS: Dropdown menu not displaying
Answer: It's because your #headerNav is set to overflow:hidden. Just remove this line of css:

#headerNav {
    …
    overflow: hidden;
    …    
}
