Hello

I've got one of these on my bench for a small repair.
It's a very interesting stereo chorus capable of smooth and very subtle effects, but also weird pitch modulations and seasick generator. It reminds me the TC SCF because they both have a modern clean overall sound, but the Elita is more dirty in a good way.
It is based on the KA5286P2 chipset, as usual in modern russian pedals the wiring is neat and clean.
It runs on +15V positive tip minijack 3.5mm, not pedalboard friendly; but I've read somewhere it could run on +9V with no problem. I guess the s/n ratio will be bad with 9V, because it's already noisy with a super-clean 15V psu.

Here's a page with some informations:

A little inaccurately read the name of the chip is properly KA528БР2

Thanks for the correction mate.
So it's not the kind of IC I thought it was:
