Well boys i think i have the receiver fix. To make a long story short, I change out the 6js7 tube and the 6sn7 and the 6h6 tubes. Boy did that ever change things around. I was told once to not really rely on a tube tester reading that a tube is good. Now i know why. The BFO change so now i have to have the bfo on the left side of the 0 of the beat oscillator instead of the right . Plus it alot easier to clarify a station in audio wise now. Plus the crackling in the audio seems to be gone now. Just to make sure its not heat related i got so freeze spray and sprayed each mica cap and there was no change. Now i will let the receiver run and lets see what happens.So far the receiver has been running most of the morning and its getting better and better with time. Time will tell. 73 and thanks again for everybody input. Rick VE7RiK
