Fleetwood Constellation Restoration Thread

If you did not disturb anything in the tuner or IF sections or subject the set to strong mechanical shock then your issue is likely that resistor or it's area...It also could be that if the B+ to the tuner has changed that the AGC needs to be tweaked to account for that.

Thanks for the reply. My first step will be to put the old resistor back in, that will answer the question of whether that is indeed the culprit. If the problem is AGC, then I should be able to get back some semblance of picture and sound by biasing the AGC line at -3V, correct?

Update: Replaced the original resistor, it started working again. Tacked in the replacement, still works. I'm running a 10 foot cable temporarily so I have a signal source to test, I'm starting to wonder if I just had a poor connection yesterday.

As it stands the set is definitely watchable but there area few things that could be improved; I'll have a look at that circuitry in those areas to see if I can locate the problems (namely contrast and jittery picture on some channels)
