  We describe the experiment PHELEX (PHoton-ELectron EXperiment) on the search
for dark photons of cold dark matter using a technique of multi-cathode counter
developed by us for this task. We present the new data, the new upper limit for
the constant of kinetic mixing and also first results of measurements of the
diurnal variations in solar and stellar frames. We outline the perspectives of
this method for the search of dark photons
