1000+ Head-Fier
The flashing is flaking, is it running at abnormally high temperatures? Popping isn’t good. I would let it run without the headphones plugged in for awhile. Did the seller include test results?
I just bought this tung sol 6080 and the getter is flaky? Also popped a few times on start up, but I cleaned the pins and it seems to be okay now, but is it signs of a failing tube? First pop scared the life out of me - I thought I damaged my HD600s
