View Full Discussion I bought this amp from massdrop about 3 months ago. A few days ago the large rear tube started arcing when powered on as can be seen in the attached video clip. Now my unit's "dark voice" background has been replaced by an intermittent high pitched hum. And the tube is transmitting static to my fm receiver sitting beside it. Anyone have any advice on whether I should be requesting just a replacement tube or a whole new amplifier unit?
