This is exciting, that is, if you call working on this heap of junk exciting! At last I'm getting some positive results from the signal circuits.
This morning the signal generator was connected to the aerial socket and believe or not signals are getting through, there's hope for this set after all.
The sound peaks up at 50Mc/s and the vision at 54Mc/s. Those frequencies are above channel B2 which are 48.25Mc/s sound and 51.75Mc/s.
To monitor the vision signal level a voltmeter was connected across the detector load resistor.
I'm sure it will be possible to retune this set to channel B1.
