Elektor Formant Modular

Hi Terje,
 
Just want to mention that some parts are obsolete and hard to get. uA726 can be found here and there but prices from 30 to 50 Euro's.

Hello everyone,
I have just been able to buy a complete set of NOS PCBs, front panels 
and lots of parts plus a cabinet for Elektor Formant, as well as both 
the original books (the first English one and the second 
"erweiterungen" German book).
Quite unbelieveable, since these things were made ca. 1979.
So I am starting to build the synth, and looking forward to both 
building and using the synth. I already have quite some experience in 
building and service of old analog synths, as well as using them. 
More info on me an my musical/synth activities can be found here:

I will check the archives, because I have three questions that 
probably have been ansvered before:
1. Are there any mistakes, errors or additions to the Elektor Formant 
books that I should be aware of (apart from the VCO "update" from the 
BF245 transistors to the op-amp buffers)?
2. Has the second book ever been translated to English, either in 
print or on the web?
3. Does anyone have a list of PCB-numbers, and what they refer to? I 
have two extra PCBs; one of them I found to be a ringmodulator card, 
but the other one only says: "EPS.9949-1". It has a right and left 
input or output, and A,B,C and D input or output at the other end, 
and it looks like two identical sections, so it could be some stereo 
effect of some kind.

Have worked on the keyboard PCBs, the keyboard controller and thing 
today. Will continue tomorrow.

All the best,
