This is quite common tube, 300B by Shuguang. Nothing really special, only white ceramic tube socket, gold plated pins, and carbonized nickel plate. Let’s see how interesting this tube when the filament is powered.

The perforated design is interesting than regular solid plate on most tube. But perforated design is not as beautiful as mesh one. We can see more glowing filament with a mesh plate type.


When the beauty is not too obvious from the side, I decide to give a look from the top. It seems we can see more interesting thing from the top side. The beauty of the filament wires attached to the top of the tube shown below.


I took another angle from the top. Well, I can see longer filament wires now. Beauty, I should say…
