[QUOTE="Jaded Faith, post: 138908, member: 1068"] Ruby's are Chinese. The main New Sensor brands you need to be aware of for this issue are Electro-Harmonix,Tungsol, Svetlana, Sovtek, Mullard and Genelex. I go through hundreds of tubes a year here and the Mullards and the Tungsols are the most sensitive to this. Mullards typically die instantly in this scenario. The Orange VT1000 is what I use for simple day-to-day testing where my better testers aren't needed. That grades on a scale of 0-15. Any reading of 0-3 will fail the tube and it's garbage. I won't return these tubes to you and try to call or email immediately. A reading of 4-5 is considered worn and this tube has a very short life left with deteriorated performance. It should be replaced ASAP. I consider a 6-9 typical gain and healthy. Anything at a 10 or above is what I consider high gain. [/QUOTE]
