Help need for Electrocompaniet The 2 channel amplifier

msdin · 25th March 2010, 01:04 PM

After just restoring my "Electrocompaniet The 2 channel preamplifier" it's now time to restore the amplifier.

What I'm looking for is some photos and assembly instructions of the internal, of the original "Electrocompaniet
The 2 channel amplifier" from about 1978.

I would like to rebuild my one that's I decided to dismantle about 20 years ago which was a fatal mistake.

I now need to make a new case and some new PCB's as these parts have gone missing all that I can find
from the original amp is the transistors, transformers, heat sinks and front panel.

What model Electrocompaniet amp is that? Do you have the service manual with circuit diagrams (schematic) and knows how to draw PCBs and make them? And what PCBs you need to remake?

I meant no offense but from what you are saying what's left from that amp, it's probably better to buy another used one than rebuilding it. It'll be a very long winding road since you don't even have the side panels or the top cover to make it look like what it was 20 years ago.

The amplifier was the original 25 Watt Class A model circa 1978. I have a set of schematics for the amplifier but no information for the PCB's. The layout was critical so to prevent it from oscillating. If I could find some pictures of the inside I would remake the parts that I missing. I' also have no problem with making new PCB's as I have all the kit to make one-offs.
