Philips audio transformers data... (Toestel of techniek)

Hi,

I'm sorry... I don't speak dutch, but I do my best to understand it with google translate

I am interested in Philips transistor radios from the mid-60s, for instance of the P or the L serie.

Some of the audio transformers in these sets are rather unusual, and I would like to know some more about them.

Is there any technical book out there describing the way these Philips audio transformers were made : type of lamination, wire gauges, number of turns, interleavings, etc. ?

Thanks for your possible help !
