The Psvane 6550A is a beam pentode with an octal base rated for up to 42W of plate dissipation. The Psvane 6550A is designed specifically for audio spectrum power-amplification and can deliver plenty of power in a push pull configuration with smooth and balanced response. The Psvane Classic Series is focused on the reproduction of popular vacuum tubes found in classic audio equipment. When designing the Classic Series, Psvane collected the most sought-after NOS tubes and analyzed each element of their construction, incorporating the most effective manufacturing techniques to produce stable tubes with excellent sound. Whether used in guitar amplifiers or hifi stereo systems, the Psvane Classic Series vacuum tubes excel in all applications. Psvane has been producing high quality vacuum tubes since 2011. The Psvane team originally formed in Shuguang’s high-end tube division but eventually split off to form their own brand.

The Svetlana 6550C is an excellent choice for users looking to upgrade their current 6550 tubes. This Russian tube features a robust plate design offering a high level of performance. The 6550C offers the classic big and open sounds that made the 6550 famous. The Svetlana 6550C works in any 6550 position. “Svetlana tubes are quite simply the absolute best. We design and manufacture our tubes, engineered for demanding high fidelity, reliability and overall warmth. Be sure to insist on genuine Svetlana vacuum tubes the next time you retube -- you'll be getting the absolute best possible tubes for any demanding application.” -Svetlana

The Sovtek 6550WE was designed to be the finest 6550 ever produced. Thicker plates, improved heat dissipation, higher transconductance, and increased linearity are just some of the inherent aspects of the new Sovtek super 6550s. 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.
