did'nt get nothing past the first coil at the 27 tube. There was a mica across the 27, replaced it. Still nothing. right in that area are 2 tar cans, 2 sections each. replaced 1 can, now got pulsating humming. Changed the other can, got loud normal operation

Funny how they can go just like that... There are a few others left in there, just going to change all of them. Thanks for your help. The cabinet is next in line.
