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.

In order for most amplifiers to function properly, amps need to have a similar cathode current. Matching power tubes allows this to occur.

To get eight (x8) matched 6550 tubes, simply order two (x2) matched quads (x4 each) and make a note in the comments section to have both quad sets match. Yes, we ship internationally.

Using the "5" rating from Groove Tubes, you will want to request a set with middle numbers. Changing a 6L6 to a 6550 may require rebiasing of the amp, yes.

Apex matched tubes are rated by plate current and transconductance. Similar to Groove Tubes, we have low. medium, and high ratings available and would be happy to supply you with the type of set you prefer. Please include an order note when making an order.
