Thanks for suggestion
Yes I have a rf signal generator and it also has an audio generator.
Tried the alignment procedure but could not get any signal after the first step. i then noticed that there are trouble shooting procedures for the radio as per attached. section 1 measuring voltage checked out
section2 revealed no signal . I checked the resisters since the caps and tubes are good and R203 reads 586 K verses the parts list of 470 K and R204 read 233K vs 130 ohms Its gets weirder .The next step for section 3 shows in figure 3 C307 (.05mf) connecting from pin 5 on the 50 A5 to pin 3 on the 7b7 it does not show this on the schemo. the current wiring is pin 2 of the 50 with a .02 mf connected to pin 5 of the 7b7.
I am very carful when replacing caps .I don't remove the old leads from the pin entirely. I cut the lead from the old cap and connect to that lead so i dont wire to the wrong pin. What controls the figure 3 or the schemo?
Also the rf coils do have continuity and seem ok
