Some (all?) Spotmatic models use the same galvanometer as the K1000.
If that's what has failed a suitable replacement part should be available.

I tried all the solution you have suggested, but the light meter is still erratic. Now I remember that the problem arose just after using a yellow filter on the Helios 44 lens: is it possible that metering the light through the filter damages the light meter cell?

Absolutely not!

Pull the battery and pretend that it is an SV. 🙂
