6h30 tubes dampers to replace Audio Research ones

Hell all
i have bought a ref110 which doesn’t have the black rings on the 6h30 tubes. So they are naked...
where to buy them ?
i know some people speak about Herbie’s ones, but i don’t want to make my sound clearer , as even if my ref cd7 is on the analog side, the sound coming from my maggies mg1.7i is everything except too warm.

i still have the black rings in my cd7, maybe move them to the ref110 and put somethig else in the cd player ?
or just find something for the ref110 but what and were ?
thank you guys

It is of utmost importance that you source the rings from Audio Research.
The right rings for the right mode/vintage of your amp.  Some were transparent silicon recent ones are made of cryogenically treated and quantum enhanced black diamond amorphous material with precisely calculated heat conductivity.
You must slide them in top down and seat them right at 1/2mm above center of gravity of that particular specimen.
Best of luck.
