Meanwhile the E1 is fixed and restaurated. When it was sold, it was in so bad condition that it was not operable. The main elko had a short and would burn the main transformer if it wasn't replaced. The condenser coil for the electron beam of the crt was broken, and some other more failures. Now it is working again, with original 441 lines video. Here are some photos of the restaurated and clean set:
