Default Re: 1948/1949 Philips type 520A television and radio

I'm certain that all the models marketed before the 520A were designed to receive the AP transmitter, no Birmingham versions. Is it possible the models 463A and 563A were nothing more than alternative cabinet presentations of the 383A?
Jon's 563A: http://www.thevalvepage.com/tv/philips/563a/563a.htm
The date code on the two TCC Visconol capacitors in the EHT doubler circuit is 477, July 1947. I'm trying to determine the date codes on the Philips black tar "goudron" capacitors. More about that later.
The contributor to this French TSF forum has his problems with those condos au goudron:
