Hi Chris
The V3 anode load is shown as R16 (Philips data) plus the two IF primaries.
R16 is given as 6k8 (In this set Philips have fitted a 2k2)
The data sheet says Va should be 195v in AM mode and the HT rail should be 285v so Ia should be (285-195)/6k8 mA =13mA
My HT rail is a bit low at 230v and I measure 12 across the 2k2 = so 5.5mA
I attach two oscilloscope displays
First is V3 anode receiving AM signal when 1mV is injected into V2 grid ( 470kHz with mod 400Hz)

The second is the detected signal after the IFT ie junction C47/R39

The compression of positive swings can nbe seen.

Any ideas please


Chris
