do I really need these things?

these aluminum preamp tube covers,
do I need these ? I think mine are rattling ! I know the amp was designed with them for a reason, just curious.
thanks

Don't they have springs inside on the tops? They should not rattle if the springs are doing their job. I would leave them on. They are shields and they also act as a heatsink. Maybe you need to stretch out the springs some.

They also reduce microphony. However, they just dont look cool so I take em off too. I put em on for gigs though.-Ig

OK thanks
I've got this mystery rattle that actually sounds just like these aluminum thingies! I'll try them off at practice but keep them with me just in case

thanks again

In alot of amps the high end will come up a good bit without the shields on - you can really hear it in marshalls. Is it good or bad? Not really - just different. You might like them off with a darker set of tubes, and on with a bright set.

I just noticed this with my Harlequin (testing for rattles, so I took 'em off)....and I thought I was going nuts:NUTS ....thanks Paul and thanks to the search page searing highs (in a bad way), so they're back on

So, how does one reduce the rattle from the tube shield? My /13 has a rubber "hat" for each power tube....does anyone know where these can found?

Thanks,

Andy
