Radios from the US are rather rare in these surroundings. So I was really excited to get this radio-phonograph through a barter with an American who was interested in my Philips HX347A.
The radio part is an AC/DC radio with medium wave (AM) only.
It is constructed for 115 V, 60 Hz operation.
The valves used, (whaddayamean? oh, toobs), are miniature 7-pin types:
35W4 rectifier for the power supply;
50C5 penthode as output stage;
12AV6 as detector and AF preamp;
12BA6 HF penthode as IF amplifier;
12BE6 heptode as frequency converter.
After I received it, I connected it to a step-down transformer and tried it. The radio worked perfectly, without an external antenna, err, aerial. The record player works, too. But it runs too slow, as it has been constructed for 60 cycles/second. I'll see if I can build a frequency converter. Would be nice..
