Opinions & experiences with tube coolers

Over the years, I have used products from Mapleshade Audio and other sources for conducting heat away from the tube envelope. Their full-length brass body placed over the tube and then adjusted, claims to have damped vibration as well as cool the tube surface directly. Pearl tube coolers are inexpensive, and I wonder if they do any sort of shielding as well. Taking unneeded heat away from the tube makes good sense to me, but does it provide other benefits?

This does nothing but take away from good sound,Get Herbies RX tube dampers to improve sound.

No to tube coolers and dampers.

No point. IMHO.

The ribbon on the Mapleshade thingies make good IC's. A little funky looking with their crude connectors, but competitive with pricier offerings.

Tube add-ons? If one's ears hear benefits...it works-YMMV

I have a few of the Mapleshade planks. Pricey

I DO appreciate the responses. Actually, I thought that there would be an abundance of those who felt that cooler is better, at least in the longevity of the tube itself. Of course, I also want to ask about the older tube shields back in the day. I know that they are not common as they seemed to be back then, but would they have an effect on tube life, keeping heat in? I value your responses and look forward to them. 

 

 Merry Christmas ALL!

Can't always rely on a cooler. Sometimes the old ways are best.
