I'm attempting to change the tubes in my Crate Palomino and noticed that the 3 preamp tubes (12AX7) have tube shields on them (metal cover/casing) Does anybody know if its safe to operate the amp without using them? Thanks!

im not a tube expert but seeing as how soo many other tube amps have uncovered tubes i wouldn't see any danger in it, however though since they have covers on them from the factory there may be a reason that they're there so, look for a second opinion on this

my 5150 has 5 of them. mines covered to. i am guessing they should be on there like ya know incase they fall out of something. because i check mine often and sometimes they are loose.

I think they provide shielding and reduce noise.

thanks everyone, I think I'll continue using them since they were already there
