Sovtek 6550WEPL Sovtek Platium Match Tube

The Sovtek 6550WD and 6550WE were designed to be the finest 6550's ever produced. Thicker plates, improved heat dissipation, higher transconductance, and increased linearity are just some of the inherent aspects of the new Sovtek super 6550's. The resulting performance advantages include 5% higher output power, increased reliability, greater headroom, and superior tone. The 6550WE features a metal-ringed base for increased power-handling capabilities.

Sovtek tubes are quite simply the absolute best.
