ARC REF2 5AR4 arcing on warmup

anyone have any experience with this? The tube arcs like crazy for a few seconds then settles down.I assume the tube is shot. I just got them from Audio Research a few weeks ago. Put the origianl Ruby AR4 in ( bought the pre used ) and no problems arcing now.

I feel lucky that the one I recently bought has no such problem. From a tech here who has a lot of experience on ARC equipment: most of the time a problem with tube equipment can be traced back to a bad tube.

I would bet your replacement tube is faulty.
