OK, anyone with experience have an opinion on these things? www.jacmusic.com/accesories/Duende/I like some of what they say there, but it's what they aren't saying that I worry about...

Made for high end stereo equipment, I assume. I always thought something like that would be good for guitar amps too, in some situations.

This is an old audiophile trick. In the guitar world we also used rubber bands or shrink wrap on critical gain stages to reduce some types of physical microphonics.

I know Mesa sells a super duper low noise 12AX7 wrapped in heat shrink. They sell it for a super duper expensive price too. I think they are just a regular old Sovtek. They were going for around $16.00 3 years ago. Geeez!

I've got a Mesa tube from 10 or 15 years ago with that heat shrink on it. That tube sounds bad in everything I've ever tried it in. Back at that time I was using a mark 3 hardwood combo. One day before the gig I bought 4 new mesa 6L6s and put them in before I went to the gig. 3 of the 4 started arcing as soon as we started playing. I left the old tubes at home so I had to play thru the bass players spare preamp and straight into the board for the rest of the night. The next night I put in the old tubes and played out the gig. I NEVER bought Mesa tubes again.

So I guess the obvious next question is can we benefit from such tube rings - especially considering we have combo amps that punish our tubes so much. Are these a waste of time on a guitar amp?

If you have a microphonic tube try a rubber band around it ... can't hurt, is dirt cheap, and may help.

Most preamp tubes don't actually get that hot in the V1 position.
On the phase inverter it is not needed and those get very hot in some amps.
Keep it to V1

Thanks for the clarification!
How about on other amps where there are 3,4, or more pre-amp tubes?
