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
My Rogue 99 needs better isolation...please help.
I'm currently using ceraballs under a Rogue 99 and found them to better the BDR cones that I was using before. Although the microphonics are less pronounced than the BDR cones, I'm curious if a combination of four cork isolation pads under a maple board used in conjunction with the ceraballs would help with the microphonics. Any suggestions would be much appreciated.
