Help need with Iskra-111
Dear All,

I was lucky enough to get an Iskra-111 bench calculator with Nixie indicator tubes. Unfortunately the power supply is defective. So I am looking for a schematic of the power supply, the values of the components and the electrical values of the power supply (secondary voltages, power, etc.) to be able to repair the power supply.

Unfortunately, Iskra has a lot of variants of the power supply. For example, the schematic that can be found at (now only at the Wayback Machine) differs so much from the power supply I have and the component values are too blurry to be readable, so this document is useless for my project.

I would be very grateful if someone had information for me about the power supply used in the Iskra-111.

Thank you very much in advance.

Best regards
