24v Soviet Vacuum Relay B1B - 1T1; Required Coil Current

[Naysayer]

I could not find and/or decipher the coil current requirement for this common 24v, Soviet relay. (datasheet in Russian). It's sold by several online vendors for as little as $30 plus shipping (>$10). The relay base is common to several configurations (SPST SPDT, etc). I found that the relay will not budge with less than 92-95mA at 22vdc.

I isolated the relay with it's own PSU and keeping the relay closed requires 75mA.

PSU is scratch from a separate 24v transformer* feeding a small FWB and then a LM317 regulator module set for 22vdc**. Module heatsink gets almost hot. Placed near a fan now so it's workable.

You get 24V by using the two blue wires only. Black would not be used. Input is 110V/220V. Output is 12V + 12V.
