Hi TA Forbes,

The Shadow meter checks out ok. My biggest concern is not being able to align the IF properly. I believe the Shadow meter / low AVC voltage is just a symptom of being out of alignment. But, as mentioned above the variable mica caps bottom out before reaching the optimum output voltage.

As for removing the IF cans, unfortunately all three are connected, and can not be removed separately. The difficulty I am having is in getting to all three clips.

Thanks,
John

Dan Double conversion is using two IF converters instead of one. This improves the image response. morzh — 07:15 PM
