Did my Rat pedal blow my input tube?

    A week or so ago I was jamming with my BYOC Mouse pedal (vintage Rat clone) and at points I had the volume and gain at full into my JCM800 2203 100w head. The amp was fine then, but then I switched to my 808 OD pedal and played for a little bit and then I heard a pop sound and the amp got really quiet. On a hunch I swapped the input tube for one I had lying around and the amp came back to normal. I know the 808 wouldn't blow the input tube, especially how I was running it with the gain off, but the Rat pedal is new to me and I had it dialed pretty extremely. Is it possible that the Rat pedal dialed like that is bad for tubes, or is it just coincidence and the tube would have failed anyway?

    Valves (tubes) are usually quite immune from overdriving, but if the device is approaching the end of it's lifespan, the stress of operating flat out can be terminal. I suspect you just had bad luck.
