Tube microphonics


Hello. I am using Audio Research Ref 750 mono blocks and they in front of my speakers but off to the sides. Someone told me on another site that if I move the amps beside the speakers and not in front of them , my system will improve immensely. It will reduce tube microphonics. What are your opinions of this and I just want to say that I’m very new to tube amps so this is something I never heard of before. Thank you all.

@fuzztone  What is tube microphonics ? Also I really don’t have that much room beside my speakers for these amps. That’s also why I wanted to know more about this before a keep moving them. 
 

@carlsbad2   Kinda both. Because I really don’t want to move those amps with the full sets of tubes already in them. Don’t want anything happening to the tubes by a bump or so. I already had one tube arc on me the first time I tried my amps when they got delivered. And it took out a resistor and fuse also. Don’t want that to happen again.    @jetter That sounds like a good idea. I will definitely try it. And yes. I did carry them upstairs but like u said there were no tubes in them. @ghdprentice Right. They don’t have rubber dampers for the KT150s. 

Update on tube dampers for KT150s. Herbie’s does make tube dampers for KT150s. They are $54 ea. So I will need a total of 16 x 2. Power output. And 2 x 2 drivers. For a total of 36 KT150s. -$1944 

@mulveling @jjss49 @jetter  Thanks for clarity on tube dampers on tube power  amps. @mulveling  Hell no I’m not gonna spend almost 2k just for looks. Wouldn’t even spend 50$ just for looks on a tube damper without it doing nothing. 

@onhwy61   I was thinking the same from the very beginning too. Plus my speakers are B&W 800 matrix. Top and bottom bass also. They act like having 2 subwoofers on ea speaker.
