John,Why don't you try the Mortite on your signal tubes? You would than have a Herbies/Mortite shootout. -Roy
Quote from: Bigfish on 27 Mar 2009, 01:16 amThanks Guys:I just placed an order for 5 UltraSonic 25's and one UltraSonic 70. Also thanks to Ted_B for the recommendation of the UltraSonic 70 with hard pads for the EML 5U4G used in my ModWright Transporter.KenAfter placing this post last night Ted and George let me know that I need the UltraSonic 30's for the 6SN7 tubes I use in the Transporter. Thus, I contacted Herbie and changed my order to the 30's. Thanks again guys and I look forward to receiving them.Ken

George:Yes, they arrived on Monday and I immediately installed them. I listened to the system for approximately 4 hours and had to leave home for business travel. Honestly, I was surprised as there was a definite change in the sound. There was more detail and a more distinct quality to the sound. For roughly $60.00 it is a no brainer investment and I talked Philistine into ordering them for his Transporter.Thanks again for publishing your comments about the Herbies and for Ted and you providing the correct sizing information.KenPS. I would also like to add that Steve (Herbie) is a great guy to deal with and ships immediately!

I would think that, assuming tube damping is actually worthwhile, doing something like applying RTV silicone to the tube (perhaps in a ring around the middle) would be the best bet. You'd just have to make sure it could stand up to the high temperatures, but I've seen silicone for automotive use that should do the trick.
Less permanent would be Mortite or Dennis brand rope caulk. A $5 package will probably treat 3000 tubes
If it works, you wouldn't want to remove it anyway.I was also figuring that you would want a good bond with the glass for the best damping.Mortite is not quite elastic enough IMO. It permanently deforms and thus will not absorb repeated movement as well as something more elastic. Also, how does it hold up to the heat?
Don't use modeling clay tho.....I think there is some plastic compound in those (which is why is more malleable) and I don't think it would stand a chance against tube heat.
