When I was switching out H outputs I notice after the set ran for a couple of minutes I would see a tearing of 2 lines on the right side when tuning on the lower UHF channels only. That was with a 6JB6A. I put the regular 6JB6 back in and the barkhausen was gone. Is the "A" version a stronger tube? Do you think what I have is another form of barkhausen getting into the IF or video circuits? How would you correct this? Thank...Jeff
