You need a occiliscope. It's not something I'd f!#@ with. You have to set it (bias)"just right' otherwise your sound will not be as good as it can be.(you can damage the amp)
It only takes about an hour or so.
Just ask to get your amp biased. Cost about $50.
6L6 and 5881's are interchangeable. But you NEED to get it biased.
