Amp plays for a long time after shut down - Marantz 1060

[marty-alex]

Hello guys!
I just got a new Marantz 1060 - it arrived today and it took me many months to find. It's completely mint, schematics and manual is included. I uncovered the unit and sprayed the contacts and knobs with DeoxIt. Then I connected the amp to some crap-speakers I keep to test the vintage - I don't wanna hurt the speakers in my setup before I'm sure everything's gonna be OK. And, yeah, it sounded pretty good...but I will be making some more tests later, that's not a point of my today's post. :music:

The thing is, when I shutted down the amp, it kept playing for next 20 seconds (or so...). My Pioneer Amp also plays when I shut it down, but never longer than 2 sec or less. If I keep the tuner on and I even unplug the 1060 from the wall, it still plays for what I call a suspiciously long time. I had quite a few vintage amps, but I've never encountered this behaviour. Is that normal for 1060? Or any idea what's wrong? :scratch2:

This is normal for any power amp that has considerable energy storage in the power supply. That means large or several large capacitors. :smoke:

The Marantz 1060 has no protection relays. Most amps would do this if the relay did not disconnect the speakers when turning off the power. Since it is an integrated amp, I guess Marantz assumed you would shut off your source before switching off?

Thanks. As always, AK rocks. :)

But still, 20 seconds sounds like a LONG time... :scratch2:

I haven't had either of my 1060s hooked up in a long tome (I've got two of 'em), but they too, ran for a while after shutting off. I'd say 10-12 seconds at least. Maybe more.

No need to sweat on this one, Marty. I betcha it's perfectly fine.

And congrats! I know you've been looking for one for a while. Enjoy that 1060- great integrated amps, they are.

Hello Marty, as it has been said, this looks perfectly normal.
Also my 1060 continues playing for at least 20/30 secs after power off... it fades.. fades.. distort.. fades again.. distort again and finally shut off :yes:

Regards,
Carlo

My ABI plays for about two minutes. Funny in that it's only got 10,000uf x 2.
