Fw: [sdiy] ETI vocoder input amps

[UKB]

Hallvard,

It sounds like you have had a long journey to get this far! I did find a zip
file with the article in it, which I downloaded but the main board scan was
corrupted and the traces were not usable.

If you could scan your copy with the fixes, that would be great but I know
its a lot of work. I am in no hurry as the vocoder is 3rd on my list of
projects at the moment. I will continue to search for the original article
in the meantime.

Good luck with the vocoder - I look forward to your announcement on the list
when it is working.

Regards


Paul
