Carbon Microcrystalline make up stabilization of the electrical performance inside of the Vacuum tube. 2, The PSVANE...

The major difference seems to be that the Psvane is far more extended at the frequency extremes,but at the same time has a far more richer harmonic presentation. Much like the qualities of NOS 845′s  In comparison to the others, the 845T, right out of the box, seems brighter. After about 10 hours I began to notice a difference. Compared to the 845B, they seem far more transparent but at the same time much cleaner. Bass tones and pitch definition are improved. String tone seems to be...
