Treasure 6SN7SE Globe: ‘I got the chills from this thing’

Feedback received from customer Noah via email:

“Hey there, I just received a Treasure Globe  6SN7-SE

I dropped it in my (Schiit) LYR+ / BIFROST and I’ve been listening to it on my (Sennheiser) HD800S. This thing is mind blowing – thanks for selling such a great tube in Canada.
I got the chills from this thing. It completely evens out the tone of these headphones while still keeping a massive soundstage. I have been using them for every genre and it all sounds good, as long as it was mastered well.  I’m going to have to get more spares . . .  “

Push pull amplifier – tube troubleshooting

Below are procedures that customer needs to complete to identify faulty tube, before submitting a warranty request:

  1. For Push Pull tube amps – 2 power tubes (either EL34 or KT88 – these are the most commonly used power tubes in push pull amps are used per channel. You may also see 2*300B or 2*845 type power tubes in recent years’ design)  Total 4 tubes are used for two channels together.

A floating piece of glass inside the tube – What is it?

If you have been playing with vacuum tubes long enough, you might have run into a situation that a new tube, shipped from a vendor, arrived with a piece of floating glass inside (see reference picture below). What is it? Where does it come from? Is the tube damaged beyond useful?
