    Tubes: 6A7 (2x), 6B7, 42, 80
    A device from Belgium, made by the "Fabrique Nationale Radioelectrique". When I got it it was a dusty and unsafe device. The power cord was rotten and digested so it had to be replaced. Inside I found out to my great surprise that the power transformer has been replaced, by a Philips type that is also in the BX510A. At first I doubted whether that could be good, in the end it was reasonably possible because these lamps have the same heating voltage as the more modern Ricmlock/Noval tubes. I just haven't made any voltage measurements in the radio yet, but I have a feeling that the anode voltage is a bit too low. The device plays softly, and there is also something in the HF part: that a channel only comes through when the transmitter signal is strong enough. But that remains to be found out.

    Also a 2x 16mF power supply electrolytic capacitor has been removed because it was already mounted dangerously and the value is not correct: it should be 8mF according to schedule. I solved it simply with two 10mF capacitors and so the matter is good and safe again. it is also a very nice thing and I am very happy with this purchase. An FNR logo has yet to be found for the radio, fitting in the two holes under the middle button.

    This radio has a pretty nice shell, it's an arch with the FNR logo on it. Behind the scale plate there is a disc that rotates when tuning. On that disc, one half is green and the other half is red. Through the two half circle bands you can see these colors going back and forth nicely illuminated when turning, whereby the boundary of the two colors is the 'channel pointer'. There are also just some asterisks on the scale that also let light through when the device is on.
