Default Re: Philips 663A combined radio/television 1948

Some progress over the last couple of days.

I didn't have any replacement ECH35's so I swapped the pair over to see if this would make any difference. To my surprise doing so has put a test card on the screen, with terrible line linearity and a curious white line to the left!

Still no audio so a pair of new ECH35's are on order, along with an EA50 signal diode which I found has an o/c heater. Work can then recommence once they arrive.
