Tube dampeners on ARC gear ... FREE TWEAK

Hi Oregonpapa. How high on the 6h30 tube should the Herbies be placed?  1/8"
from top of tube or all the way up?  

All the best. 

Hi Frank

So you didn't follow the all the way up to the top of the tube placement like the ARC rings?  Did you try them there?

FWIW on all the RX rings I have in my system I've never found the 1/3 placement to be optimum. On my amp on all four 12AX7s exactly one and a half inches from
the bottom of the tube which is almost to the top of the 12AX7. On all 12 KT77 tubes right at the getters and same with the 6550 tubes in my Ref 40. 
ARC recommends damping placement all the way to the top of the 6H30 tubes. I've not put the Herbies I have had now for well over a year on my 6H30 tubes mainly due to my disability. 
FWIW You might try the top of the tube placement and see if you have improved sonics with your RX dampers there. The 1/3 placement is just a starting point Herbies recommends. The vast majority find differing placements are superior. 
Just thoughts. 
All the best

Hi Frank
thx for giving it a shot and being so great!  It's you that's the reason we're trying this stuff to begin with (starting this great discussion). 
Ive used many disc mats over the years especially versions from Marigo. My current drive -PS Audio's stupendous DMP has made me rethink using mats. I've not felt the need for one since introducing this into my system. 
All the best

Thx Frank. You're the best. 👍👍

Frank as I expected.  Nice!  Thank you for trying that. Glad it improved your system
once again. You're like me. I listen very early in morning. It's the only time I have enough energy or lowest pain levels to be able to do so. 
I have to wait until I can be healthy enough to get my Ref40 out of my rack to do this. ☹️

Can't wait now. 

Thx again Frank. You rule brother. 

All the best
