Philips 836A “Arbeiderskastje”(1934)
The Philips 836A is a small radio from 1934.
Its nickname “Arbeiderskastje” (“workers' case”)
means that is was easy to use and relatively cheap.
Still, its simple wooden case is veneered elegantly.
A close look at the tuning dial and controls.
The 836A comes in a simple plywood case.
Despite the nice veneer, it is a square and simple radio.
It is a tuned RF receiver with
two wave bands: LW and MW.
It has three controls: volume, tone and tuning.
The volume is controlled by setting the bias voltage of the
first RF amplifier, which controls its amplification.
There is a small rotating tuning dial showing the wavelenghts,
without station names.
The valves are early types with gold paint and 4V heater.
Unlike the pro-electron types used in the
and the Mende 315W,
these older types have a 4 and 5-pin (B4 and B5) base:
|tetrode as first RF amplifier,
|tetrode as second RF amplifier,
|triode as detector,
|penthode as output amplifier,
There is no tuning indicator.
Being a tuned RF receiver without reaction, it is quite easy to use.
But selectivity would not be great, despite the
“Superinductance“ large (Hi-Q) tuning coils.
But hey, this is a 1934 radio, from an era when the Superheterodyne type of radio,
like the 1936 Philips 456A
was only beginning to
conquer the world.
I bought this radio through an Internet second-hand-goods site in november 2007.
The seller told me he had bought it from another
collector, who has carefully restored the radio and redone the French polish.
He was not sure if the radio worked at all.
To him, it had been a piece of decoration.
Because the inside looked so well, I was willing to buy it.
A look inside. Elegant E455 and E462 valves. Large “Superinductance“ coils.
At home, I gave it a nice place.
I will try it in due time.
