Started to replace some tubes. I also tested the tubes I was replacing and noticed that the 12BH7 R-Y Demod tube has a cathode short. This could explain the absence of red. This short didnt show up on the hickok 600a, but it did show up on the WT-100a. The WT-100 has an extremely sensitive shorts test so I guess it was able to pick it up.
