Hi! I was in the proces of changing powertubes and wanted to check how the original tubes were biased, before changing. All tubes measured very hot (~60mV) except tube 3 which measured out of this world (above 300mV). I tried changing that particular tube, which gave the exact same result except that this time the power tube failure light came on (I didnt wait for it to reach "max" mV but it was heading only upwards).
Is this a "typical" case of fuse blown, or is it indicative of some of the more dreaded arcing ?
Best regards
