Electrocompaniet EC1 help requested

BEARD · 11th December 2006, 02:51 PM

Recently I bought an Electrocompaniet EC-1 preamplifier.
Unfortunately someone has been tampering around with it.
The power supply transformer is missing and several copper tracks have been cut. several capacitors exchanged.
I would like to restore it to its former glory.
Can anyone help me with a service manual and/or schematiscs for this beautiful Norwegian piece of electronics?

Thanks!

Best wishes, Jac

Not sure if this is useful but I put "Matti Otala" in Google some years ago and ended up at a good site run by some ex-Electrocompaniet people who had at least some schematics there. I also recall others speaking positively about the official commercial site. I know you have to pick the right words for the DIY search facility to give of its best but I'm sure there are existing threads that will be helpful.

Thanks for your comment.
I was not successful in finding what I need.
I requested Electrocompaniet itself for help, but they were not willing to do so....
Definately not a plus for Electrocompaniet!

The existing Electro threads also did not show me to the solution...

I will keep on looking for the schematics (and hope someone can help me finding them).

Best regards, Jac

Hello,

No, that is the original 25+25W power amp.
Unfortunately not the EC-1 preamp.

Best wishes, Jac

EC have new owners, (and mooved), and I would guess service is difficult with a lot of the "pre-historic" models...

I have one with a manual. I will check the manual for you. If possible, I will scan it in and email it to you.

I guess I can consider selling it too since I have not used it in 7 yrs. long story..

give me your email privately I guess.

Hi

Would you be able to take a photo of the internal mess?

Let us see anything we can help.

Thanks

Thanks doanh and ben goh,

I have sorted out the interior so far and replaced all electrolytics.
The transistors measure ok, as well as all other components, but still it is not working properly.

Since it is quite a complicated circuitry, I cannot proceed without a proper circuit diagram.

If you would be able to send me a good scan, that will certainly help!

I am a relative new user and it appears that I have not made enough posts in order to email...
Well in that case: my direct email is jac@nbtv.org

Thanks for your help!

Best regards, Jac
