Hello,

first post here... and I can't read dutch ! Sorry to have to write in english...

I have these pictures of a Philips (very probably) audio amp section. It comes from an unknown device (radio ? car radio ? recorder ? turntable ?...).

It is chassis ground negative... fairly uncommon these years, but I know that, for instance, some Philips radios, like L4X26T, P3X51T... were then already ground negative.

It uses 4 transistors (AC125, AC126 and 2 AC128s, in this order), and 2 transformers (a driver and an output transformer). It's a push/pull amplifier.
Transistors heatsinks are attached to the transformers. And the transformers are of the EI type.

Output power is around 0.75W. Works on 9V.

My guess would be... A Philips board, from 1963/1965 (from the transistors). But that's all I can say so far... I would like to know precisely what unit/device it comes from.

Would you recognize this board ? Or would you know someone who could help me identifying it ?

Thanks a lot for your help !
