    Many years ago I met a project on the pages of Elector called "Дelta Delay" that is a digital audio reverberator.But it so happened that I lost that number and now I do not know how to find this article.

    Can you help me?

    Do you have any posible year then this design was published. It look quite old school. By the way. Your electrolyte caps are from 1974. So thye are most probably dried out by now and need to be replaced.
    If you send me a year(s) I will look in my Elektor collection. I have every issue dating back to about 1970

    I can not remember the year, but remember that the title of the article was "delta delay". I think the period is 1980-1995... perhaps!

    Ah thanks for narrowing it down to about 15 years that was helpful:p Well I will see what I can do. In the last number of every year they sum up all the projects for that year. So I can take look in my collection. And who knows maybe I am lucky and find a vintage Playboy magazine hidden in there. Not that I have ANY idea on how that would have ended up in my Elektor collection of course

    Used a delta modulator chip.

    I have gone through Elektor magazine annual (English version) project list from 1974 to 1999. And I could not find a matching project. They had a digital reverb project in 1978. But the circuit board do not look anything like yours. Can you remember anything about that issue of elektor like other projetcs. They had a module based synthesizer in 1977 http://dl.lojinx.com/analoghell/ElektorFormantMusicSynthesiser.pdf with a reverb section. But your circuit board does not match anything from this
    Elektor also have forum. Maybe you can ask for help there for help
