I would suggest that you may have some weak tubes in the video i.f. strip, if you have any extras try replacing them one by one and see if it improves.

Thanks, Eric...I will try flipping/rotating the trap. I probably have some 6AG5's in my tube stash at home, but I may order 4 of em anyway since I have checked the vid if section pretty well at this point and I'd like to see this set working well before going back home next month.
