Fridor 522

Our Department and University.
See my other radios too! (Here is the next one.)

A by all means average European wooden table radio of the early nineteen fifties. Everything on it and in it is plain and simple, with the exception of the little brass crown mounted on top of the slide-rule dial; the crown brings it among my wife's favorits!

Sticker on the back says ``Philips licentie'' and the chassis ressembles that of the Philips BX321 remarkably. The latter radio was produced in 1953, but the Fridor is clearly a predecessor of that design because it uses `Rimlock' tubes while the Philips uses some `Noval' tubes already.
Here is a picture of the chassis:
