There are several sources of tubes on the rise in this day and age, actually producing more old models than ever before. One is Antique Radio Supply, another is New Sensor. Tubes are seeing a revival because they sound better than transistors.
I had two amplifiers in my shop, one was an old mac tube amp, the other was a very expensive Onkyo. When customers came to the shop, I asked them to listen and decide which amp sounded better. 100% of the customers picked the tube amp as sounding better.
Tubes do rule. Long live tube amps.
