Default Re: 1940 Lorenz Textophon wire recorder

Latest news...

All canned and paper capacitors are now replaced. I kept the old capacitor tubes and fitte new ones inside. As they were smaller I padded with tissue and put some wood glue on the edges. Once solid, I coloured it in black so that it simulates the old tar.
Now the fuse no longer blows !
I can now engage the rewind option without trouble. The amplifier works fine.
The last trouble to fix, and of course not the easiest, is the mechanical system which engages the take-up reel clock-wise and releases it counter clock-wise in rewind mode (so that it's only maintained by light breaks).
I tried to turn the take-up reel manually and yes folks, I got some sounds !
So the machine is pretty ready now, I only have to understand how the take-up reel system works and how it can be repaired. All I can say is that it's either a quite hard task, or just something very easy. A technical documentation would greatly help but with such rare machines it's pretty impossible to find.
Last: my machine is model BW4. Seems to date circa 1942.
