Re: Philips 663A combined radio/television 1948
It's a very interesting transformer and highly likely to be wavewound. The one in mine is potted with either wax or pitch I suspect. It's now gone off for rewinding (would love to see this process) so I won't get to see what lurks within. Out of circuit the primary is reading low. 58R when a figure of 80R is quoted. The secondary (2.7R) is spot on. The scan only failed once full EHT had been reached during the restoration, so would suggest it simply couldn't cope with what was being asked of it!
