My Rogue 99 needs better isolation...please help.

I have used the Octal Tube dampers from Vintage tube services with great results. They have a website. not sure of address.

Another vote for Herbies Audio Labs Halo-rings. I use them in my Rogue 99 with immediate positive results. Recommended .

Thanks to everyone for the suggestions. Jphii-I'm using Ken Rad VT231'S with Halo rings which helped with the microphonics. Maybe I should try different tubes? Suggestions? Jeffcott-Where can I find info on the IsoBaseK and would a base with sand work better than a maple base? Are the Ceraballs considered a decoupling device? Finfinder- Which tubes are you using in your Rogue 99 and what does the rest of your system consist of? Thanks again in advance!

I have a Rogue 99mag. and you cannot stop the microphonics of the tubes you are using, unless you remove them. I love Tung Sol round plates but I cannot use them because of the microphonics. I have gingo balls under it and tube coolers on them and still they will be noisy, sell them. Get some Slyvania 6SN7WGT's are your best bet unless you can find some non microphonic round plates (they are the best in it, I think). Randy

Until recently I owned a Rogue 99 Magnum and the best sound it produced was with the following: 2" hard maple shelf on top of Vibrapods with 1"x3/4"x3/4" zebrawood blocks between the maple shelf and the bottom of the 99 chassis (that's the chassis, Not the 99s feet) plus Herbies tube dampers on all four tubes. The biggest changes came with the Maple shelf and zebrawood blocks. In this application the latter were significantly better than BDR cones (either #3s or #4s)or Vibrapods directly under the 99. My wife and I did several evenings of listening comparisons and found that Zebrawood or teak wood sound best - clearer, more vivid, deeper and tighter bass, more effortless presentation. I know it all sounds weird about the wood blocks and I was skeptical even after reading the article in StereoTomes.com regarding electromachanical convergence, but there was a clearly audible difference; not at all subtle. And it is inexpensive to experiment with wood scraps from a woodworking specialty source.
