What are you using to look at the outputs?
Can you inject a 26 meg, AM modulated signal into pin 1 of 6AU6 4th VIF and see something at Photofact test point marked diamond A with a TV grade scope? All the points you've noted are pretty low impedence and no gain so I would not expect to see much without a good scope. The trouble may be elsewhere. Measure the AGC at the first and second VIFs. Too much AGC voltage will cut off the IF strip. Don |
