Hi,
Are you in the Netherlands (..viss
er )?
If you are from another country, we have to know where these strange voltages
were in use.
Japanese sets had 100 - 120 Volts, Spain had 125 and 220 Volts, Australia 230 - 240 (mostly).
There has to be a language given on the front and on the back of the set.
TX points to a dutch fabrication.
Philips-Sets from Sweden and Spain are german made (TD.....) at that early days of television.
Western CCIR-countries used 220 V, mostly.
Belgian sets have a 4-strandard switch in the center of the controls.
Regards,
TV-collector
