Re: 1948/1949 Philips type 520A television and radio
The Philips 520A has a circuitry quite similar to other Philips sets of around that time, like the 563A and 663A.
A big difference is that is has no mains transformer, hence the special valves to make a 0.2A heater chain.
Indeed it would be nice to see a picture on it!
