Do you have a Hickok tube tester handy,or a friend with one.
Testing them is the only other thing I could think of.

Cayin TA-30, Tube causing smoke
I recently purchased a quad of Siemens EL-34 tubes for my Cayin TA-30. For some reason, smoke keeps appearing from the #1 tube socket. It doesn't not matter which tube goes in there. It gets more bizarre, other tubes (the original Cayin's, Winged C's) do not cause any smoke. What could be going on here? Any other TA-30 owners experienced this? I have heard of JJ's causing this in other models. Any help is appreciated.
