Comments about Svetlana 6550 Tube:

Overall, pretty good tubes, a little too mid range-y for my taste ,but a solid tube overall. Not matched but close 2 were reading 32 , one read 28, the other 29 so pretty close,I guess I'll try the tung -sol next time . or the hard instead of the medium. They just didn't give my amp the growl that new tubes usually do .


Svetlanna 6550s sound great.

    Comments about Svetlana 6550 Tube:

    These tubes sound great. They dont sound as good as winged c's, but the price for these is unreal. I wonder how long they will last. I play bass about 6 nights a week, so I need some durable tubes, I hope these are up to the job.
