4fun ,
Is model number HK650 correct? (no missed zero at end, i.e. HK6500)
I have manuals for 153 Harman's amps and receivers, but no 650.
And no listed at company web service.

Yes, model number is correct!
This is how it looks like:

I have seached a long time for this manual/schematic and I suspect that this model may have been relabeled for specific markets.
I will post some inside pics from amp very soon.

Carlos,

Some more pics coming...

I don't have not this amp where I am now so detail pics coming later....
This amp is my personal amp that I found good enough to ceep.
And not having schematic is real pain.
Ok, one way is to reverse draw schematic from layout but that is last resort......:dead:

I am always interested in imaged forfun, and i think its a pitty that our

forum cannot have audio.... small movies capability..flash movies, as i have produced many things using flash movies and some asf files with audio...explaining things to friends, and receiving instructions from them also.

Text is nice...images are something wonderfull..and if they have motion and audio...well..this is the highest dream to our communication.

Unfortunattelly.....bandwidth is the problem...not possible...or ...too much expensive.

Thank you...i will search for your schematic...i will be back!

regards,

Carlos

the 670 may be more like HK650

HK670 was 'the follower up' to HK650

It is a pity that we cant get HK650 service manual
Only the other ones.

I have an HK650 myself,
but has gotten into trouble with StandBy circuit.
Will go into standby and I cant start the amp!

I wonder if there is something triggering an error.
In the output protection sensor.
And so the amp will shutdown to protect.
Anyway, result is I cant use this amp ..:xeye:
Until I can find the problem.

What I have noticed, is the upstart relay is effected
by my TV Remote control!

any ideas what this may be ...😕

Does your amp look like mine on earlier posted pics?
I have also looked at your link before, but HK670 on HK site is a receiver, not an Integrated amp.
Here in Sweden HK650 and HK670 existed in market back then, with HK670 beeing the bigger brother of the two.

Maybe models have been relabeled as I mentioned earlier.

However I have now ordered manual here in Sweden so hopefully I will get the right one. It was fairly cheap to🙂
