The rings will straight melt to the tubes on the paramount. At least they did on mine.

They didn't burst into flames or anything, but the covering definitely melted. Didn't permanently stick to the tube either, but again it did melt. I found a seller on amazon who had them for like $5 a piece. So not a huge monetary investment ruined either. 

Probably just strip the cover off powder coat them, and wrap them in teflon.

They didn't make a huge difference anyway. I just think they look cool.

A couple rolls of Teflon plumbers tape, might be enough to keep them from melting...John

I realize that this doesn't exactly go in this thread, since I am talking about my Quickie, but I have tried the Herbies tube dampers. Since they wer mentioned previously in this thread, it seemed ok. Having said that, I have a short term impression about the results. With the 3S4 tubes, damping of any sort is beneficial as compared to nothing. As much as I enjoy these tubes, micro-phonics are in full swing and can even lead to a harshness of the treble, as well as a muddiness in the bass.  Suffice it to say that tube dampers did as much as anything else I've tried, with an improvement in the treble harshness. I can now turn the little Q up higher w/o fear of ear pain/wincing. You know, waiting for that part in the song that is as edgey as a rusty razor. Less offensive, but quite welcome is the increased bass definition that I heard. Back to notes not thuds(not quite that dramatic but you get the point). So, at such a low price, these dampers are one of my no-brainers, or ,or, you can continue you Frankenstien experiments ERIC,,,,I won't judge.

I tried the Herbies Tender Feet.  To me I notice no difference between them and the sorbathane feet.  At least the Tender Feet will not destroy the finish on my furniture.

Deb,
   I'll second that! The Sorbothane has to be watched for it's wicked traits. I've ruined a couple of paint in the learning curve. I might try the Tenderfeet....we'll see.

I've been tweaking all day. Had to re-tube the Transporter. The Beepre is so transparent I was hearing 1's and 0's.

The old preamps didn't resolve as much detail so I tubed the Transporter to give me more detail. I had to dial it back for the Beepre.

Just put 3 Mapleshade Isoblocks under the Beepre. $24 for 4. No marks on the shelf from Isoblocks.

That brought everything together! Beautiful, musical mid-range, great bass and flawless highs.

Now how long can I keep my hands off? I might need the Vikem rings....

Yeah, the damper rings may not be ideal on the Paramount.

I just happened to read this thread after returning from being away for the weekend.  I read where sssly's damper rings melted onto his tubes.

I turned to look at my Paramounts, onto which I'd placed some of those same rings.  Turns out I'd left them on all weekend long while I was gone.

Fortunately, it made it easy to lift the rings off (with some cloth insulation - they were warm!).

Turns out, they kind of melt and scorch or burn....otoh, they're easy to lift off when hot.

Vibrapods with cork circles underneath to protect the shelves. Don't notice really much difference vs the stock feet. But can't hurt particularly since the BeePre shares the shelf sith the rumbly idler wheel tt.

Sorbothane has different densities, as you already know. At the Sorbothane website there information regarding which density will accomidate the given weight.

A quick update, I'm happy with the Tender Feet purchase.  The other halves that Dan had recommended worked well but are less than 50% of their original height and mark up anything they are placed on as others have observed.  The Tender Feet make as much of a difference and hold their shape without marking what they are placed on.

EDIT ** - Asked and answered.  I'm a dope.  it is 2am, so I don't feel too badly.  the other sizes were different weights. Here is the new link:

https://www.belart.com/bel-art-f18307-0005-round-0-5lb-lead-ring-flask-weight-with-vikem-vinyl-coating-for-125-500ml-flasks.html

So apparently since Doc released his secret regarding the .5lb tube damping rings, Bellart has widened their offerings to include different width flask sizes.  Not being up on my standard lab grade equipment measurements, anyone have some guidance here?  The link provided :

http://www.belart.com/shop/183070005-vikemreg-vinyl-coated-lead-ring-p-183070005.html

Is also no longer valid, but after 3+ years, not a surprise.

Thanks in advance!
