Brand and Type: Philips LX401UB-10 - portable
Produced: The Netherlands 1951. The price on introduction
was 245 guilders, reduced to 208 guilders one year later.
How could people afford these things in the early years after WWII, I often wonder. A moderate salary didn't exceed
a 150 guilders a month. We had to wait until the sixties before wages were doubled every year....
Cabinet: Brown bakelite (Philite for patent reasons?) with a cream metal front.
Tubes: DK40 (osc./mixer) - DF91 (IF-stage) - DAF91
(detector/preamp) and DL41 (output). A strange mixture of 7-
and 8-pin tubes.
Power: AC/DC 110 or 220V, or batteries 2x 45V resulting in a B+ of 90V and 4x 1.5V for the filaments. A sticker inside says: As the anode batteries have a 4-6 time longer life than the filament batteries, the former should not be replaced before four new 1.5V batteries have been tested. Sounds fair to me.
Bands: Medium and long waves.
Controls: Simple: Volume/on/off and tuning, and the switch in the upper front is for the bands.
Obtained: From a sale at the site of the Electricity Museum in Nijkerk, The Netherlands, in May 1986.
Condition: While cleaning it, I had the misfortune to drop the empty case. Of course it had a crack from that moment, but I could repair it so that the crack is now almost invisible. That's why a 7. I repainted the metal front and replaced the missing dial "glass" by an acrylic piece, it's probably better than the original. While the original gets yellow and scratchy in time, this one doesn't. At the top it has a 90 degree angle, I used a heated metal pipe with the right radius to bend it. Maybe you'll think this isn't the right way to fix things? Ok, just find me the right dial glass and I'll replace it.....
Working: Just fine after replacing the output tube.
