Hi
I have marconi 2955b test set. Passes all selftests.
Problem is that output AF level does not correspond with setting... Level is much higher than set.. ie: set 400mv but output is 2.7v
I tried follow service manual adjust Ab6 card R1 potentiometer till get correct voltage, however selftest fails on modulation 3.x selftests as the level is too low. I have to go back to the previous level to get selftests fine again
Furthermore, manual states u can set af level to 1v while my 2955 cannot go so high in menu.
Any ideas?
Thanks
