Denon Verstärker kaputt

Actually it doesn't HAVE to take 2 weeks to kill an amplifier. You can do it in 2 MINUTES if you do your best
I know only Denon PMA-700V and that's a fairly old amplifier. I wouldn't be surprised if it needs a re-cap badly (Replacement of defective Electrolytic capacitors).
Old, defective cap's makes the amplifier unstable and can cause oscillation that will kill it in seconds.

Of course there are also the obvious user-faults like
1) connecting defective speakers
2) shorting out speaker-cables
3) playing with too high volume until a speaker-unit shorts out and overloads the amplifier.

...list goes on.

If you, or a friend with more understanding of electronics, want to take a shot at repairing the amplifier, I can help with the service-manual. PM me with your e-mail address for a free pdf-comp.

It's really impossible to say anything very intelligent based on the info you give .except, YES, es kann sein.

Es dürfte sich um den PMA-700AE handeln. Da ja vermutlich die Verkabelung vorher OK gewesen und nicht verändert worden war, m.E. ein klarer Fall: Zurück zum Händler damit. Ist wohl ein Frühausfall, Badewannenkurve läßt grüßen. WAS da nun genau abgeraucht ist, tja, aus der Entfernung schwer zu sagen.

Umtauschen, es ist ja Garantie drauf.
