From what I hear, these tubes are interchangable on most amps it seems that the 6550 is the least loved tube of the bunch. What are the sonic differences of these tubes? Thanks in advance for your reply.
The "Electronic industry" (Ei), has been rebuilt, however, the economic "sanctions" are still in place, and who knows how long? I may be able to get some KT-90, and other Ei products. E-mail me with the questions if interested!
