I did find that Decca did a separate FM Tuner with 5 Valves ECC85, EF41, EF41, EB91 and EM80. The g2 volts is about 90v (as I suspected).
Do unplug and replug EF41s as the sockets can go iffy.
There was a German VHF-FM tuner with semiconductors rather than EB91 that uses two EF41 and ECC85

It might have been this Decola: https://www.worthpoint.com/worthopedia/d...-533347888
Perhaps 1959 and simply called the Stereo Decola. Not in R&TVS as far as I can see (I have possibly all of them up to 1976 (a 21 volume set plus early sets, maybe 33 books).
The well known Decola models are 1947 - 1950 ish. This would be a rare monster one, though the EF41 choice is odd. Only really in earlier German VHF sets as the novals in VHF from before 1955.
