Electrocompaniet Anniversary Amp: Looking for some data

Redwingnine · 30th April 2011, 10:16 PM

I recently picked up a Electrocompaniet Anniversary amplifier, along with a EC 4.5 preamp. Looking for some information on the amp. I was told that it is based on the AW 75, but that is all I know.

Would like to get a schematic for this, as I would like to change out the electrolytic caps. It has a bit of a turn on and turn off thump, but the sound from this is very clean, open, and transparent.

I have many Electrocompaniet schematics but am not sure if any would be good for you.
What is the year of fabrication?
Can you post a picture of the inside of the amplifier?
This way maybe I could recognize the boards.

I am not conviced you will eliminate the thump by replacing the capacitors.
I have had many Ampliwire II and they all generated that thump at turn on.
