Well You got alot of possibilities for having poor sensitivity. A weak tube, an alignment issue, or an improper voltage somewhere can give you these symptoms. How to troubleshoot? First get out the voltmeter check voltages to see if they are what they should be as per the diagram. Test tubes. Get a signal generator and see how sensitive the RF and IF stages are. Does it seem to pickup just the very strong stations in your area? What sort of antenna are you using?

ps Please use caps and periods. I'm not trying to be a wise guy
but makes it a bit easier to follow where thoughts start and stop.
tnx

Now I think I've got!
