These are the top 10 albums of German Krautrock and Progressive Electronic in the 1970s as it was rated altogether on RateYourMusic and ProgArchives in March 2019 (if only including one album per artist though):

Faust (D) : Faust IV (1974) 11,7 (7.100 r.)
NEU! (D) : NEU! (1972) 11,5 (9.000 r.)
Amon Düül II (D) : Yeti (1970) 11,7 (6.300 r.)

Kraftwerk's Trans Europa Express (1977) should be a part of this list too. If not considered progressive enough, it could alternatively be Harmonia's Deluxe (1975).
