[Tubesforme]

The tubes I put in this receiver were being used in another receiver which had no problems so I know they are good. First I put in a good used Philco  transformer and it opened. So I purchased a new one from AES and it also opened so I purchased a Hammond and it is the one that is acting up now. I had originally suspected the tube, but that has been eliminated by taking the pair out of a working receiver. The transformer from AES lasted a little over a month. The same problem is starting again with the Hammond transformer. That is why I am stumped. I originally thought that the tube was causing the problem and later thought that the winding in the transformer was the culprit.
