RE: Tube Socket Reliability

Peter
I don't think the issue was the socket..What can happen at times and especially with newer tubes is,a few loose particles of mass inside the tube can get lodged between the control grid and one of the other elements and when that happens,you will have not any control over electron flow from cathode to anode and it will red plate..Just taking the tube in and out could have dislodged whatever was in there and made it work again.
You can also have a finicky coupling cap that has intermittent leakage. Do this,take your meter and check to see if you have the minus 37 to minus 40vdc on pin 5...If that is present,lift the coupling cap on the side going into the suspect socket...Measure the DC voltage from the open end of the cap to ground..If it reads more than two tenths of a volt,change that cap..
