need help with tubes!

[dug]

I have a set of sovtek 5881 wxt and it says they can be put in the place of 6l6s.
I've also heard that this is not a good idea.

The other guitarist in my band is needing tubes for his 74 silverface twin. I was wondering if we could use these.

well I'm gonna try em.

If his amp blows up I'll make sure to tell him its his fault. 

thanks

Yeah, we'll need to hear about it!
