Interesting Output Stage?

[Mike Watterson]

Yes, Lawrence, you can see how Saba adapted it to have switchable push pull mono (high power lower distortion as 2nd harmonics cancel and most listening) and single ended stereo (less than 1/2 power per channel, only some records and only if external player available).
I think a Grundig uses a similar circuit to Ferguson. Their Majestic brand in USA was one of the first European made stereo Radios (MPX Radio Stereo came later in Europe than USA).

Thanks for the 1958 link!
