I have a Sencore TC 136 tube tester. I am trying to test a 3DG4 Rectifer tube and it is one of the tubes that you have to short pin 1 and 2 per the back pages of the tube chart. It states that there should be a short on G and H-K. I have tested two tubes and I get a short on C and H-K. Not sure if this is a misprint or what but if anybody has a Sencore and a 3DG4 rectifier tube that they could try and report back it would be greatly appreciated.
