Thanks to all who replied. I removed the Sylvania tubes again and replaced the NOS tubes that seemed to have caused the fuse blowing episode. I replaced them one by one and measured plate to chassis as each was replaced ......no shorts. Then I turned the TR3 on after inserting each NOS tube....NO fuse blowing. Now all three NOS tubes are in the TR3 and it is still making sound.

I suspect that a foreign particle must have shifted in shipping and lodged between the elements causing an internal short. Also, while in process of removing the tubes and turning then around and up and down the minute particle might have become dislodged, clearing up the short. I hope that is the case.

NOW ON TO MAKING THE TR3 MAKE RF!!!!!!!!!!!!!!! Wish me LUCK!!! Thanks and 73, John, K5PGW
