Angry H-K AVR3000 loses memory among other things

Ciao!

I bought a used AVR3000 that loses its memory regarding the radio FM-band when the main power is switch off. Thats not all, when using the Tone in & Tone out I lose the right front channel.

Have anyone else had this problems??!!......................
If there is anyone who has the Service manual for AVR3000 I would like to recieve a copy if possible, thanks. //Flyier

There should be a back-up capacitor 4.7MF that needs to be replaced.
As for the right front channel, press TONE MODE and RDS buttons simultaneously in standby.
Bear with me, this tip is from a repair database. No guarantee it will work.

Thanks for the tip, I'll try the easiest solution in Standby first.
I think I should have the schematics before I try to change
the capacitor.

Is there anyone who has the Service Manual / Schematics to
a HK AVR3000 ?

The schematic might eventualy show up but a picture of the board could help us to locate the cap. Could you do that?

Hugo,
thanks for the tip to reset the amp, it worked as a charm. I still have the problem with the memory (cap.). A pic will be comming soon, haven't got the time yet. BR // Flyier

PS. Does the AVR7000 and 3000 have the same solution and location of the memory back up with 4,7uF cap.?? In that case I've got the SM. DS.

Glad one problem is fixed.
Expect a 4.7MF instead of 4.7uF. Don't know about the 7000 but the schematic might help you to locate the cap.

Hugo,
not that I know but isn't 4,7MF a little big? (If M=mega?) , anyway I'll try to open the amp up and maybe take a foto today. BR // Flyier

Not at all, this will give you an impression of what it should (could) look like.

Finaly, I've got the SM I think for the AVR3000 (as far as I
can see it's the same as AVR310). This helped me to locate
the cap and hopefully there will be enough space to replace
it easy.

Many thaks Hugo for the help and the tech spec for the cap.

I will be back to tell how it went to change the cap.
