NAD amp distorting heavily after running a bass guitar thr..

[Guest]

Archived from groups: rec.audio.high-end (More info?)

My NAD 214 stereo amp is dead or dying. Any signal I run through it is
extremely distorted and I have to turn up the volume to even hear that.


Beginning a few months back it would sound fine and then all of a
sudden die and the sound would become horrible distorted. The time it
takes the amp to go from working fine to distortion box continually
shortens from 20 to 10 to 5 to 2 to 1 minutes. Now it doesn't work
for anytime at all.

I haven't been playing nice with it recently. I have run a microphone
and bass guitar through it. However, the amp had experienced the
problem I described above before this.

So my question is this: Is there any fundamental reason why running a
bass guitar or mic through this amp would hurt it? Also, does anyone
have any idea what might be wrong with my amp.

Thank you!
-Jon

Ps here is my setup in case it's helpful.
NAD 214 Stereo Amp
NAD 512 CD player
Adcom preamp
KEF Q55 speakers
Monster XP cables

You're sure it's the amp and not the speakers ?

No, unless it was a very high output active bass and a badly-designed
amp. Standard bass pickups rarely put out more than 100mV on average;
mics even less.

Dodgy solder joint, probably, which breaks a connection as the amp warms
up and the PCB expands. Open it up and take a look - whilst it's powered
off!

Jon, I ran a bass through my stereo in the late 80's. It fried my
speakers. I would check them out first. Live instruments are too dynamic
for a steroe amp or so I was told.
