Jul 28 at 14:12 comment added Spehro 'speff' Pefhany @balu I have looked at your measurements. Please have a look at the capacitor type and value. The 2N2222 base-ground voltage is not unexpected.
Jul 28 at 14:12 comment added balu Thank you very much for your answer, I rechecked the polarities. I will order some 2N6028 from another supplier, since some other sources on the internet seem to have problems with the 2N6027. In the meantime I have added some voltage measurements to my initial question.
